If you are interested in cryptocurrency mining and have been wanting to understand the topic for a long time, but due to the volume and complexity of the issue, you have been putting it off all the time, today you have a great opportunity. The article contains basic information on cryptocurrencies for dummies. It is clearly explained what Bitcoin, mining, blockchain and other obscure words are. Why do miners buy video cards, what are mining farms, why is cloud mining needed, and is it really possible for everyone to make money from it? Sounds interesting, doesn't it? Let's start with the basics.

What is cryptocurrency

Cryptocurrency is a type of virtual currency created and controlled by cryptographic methods. It is not controlled by any government agencies and is not confirmed by anyone's power or authority. But due to the fact that its basis is cryptography, you can safely carry out operations with it.

All that affects its price is demand. You can use it like regular money: exchange it for other types of currencies or even pay for some goods and services. Where does it come from? There are the following methods for mining cryptocurrency:

• Creation;
• Purchase.

Creation will cost less than purchasing, but will take longer. The process of creating cryptocurrency is called mining. Mining consists of generating new blocks of information according to algorithms established by the system and receiving a reward for this in the form of cryptocurrency units.

It all started in 2009, when Bitcoin appeared. After Bitcoin gained popularity, analogues appeared. Alternative cryptocurrencies that work on the same principle, but with different mathematical algorithms: Etherium, Ripple, Litecoin, etc. They are called altcoins.

What is cryptocurrency mining and how does it work?

Let's figure out what it means to mine. In simple terms, as soon as a person installs mining software on his computer and opens a wallet, he becomes a participant in the network - a miner.

Software is needed to connect to the system and start mining cryptocurrency, and a wallet is needed for transactions. The wallet will manage your balance and the keys necessary to sign transactions using an electronic digital signature. The important thing is that the wallet does not contain any real owner data.

The principle of cryptocurrency mining is the absence of any central control; all network transactions are written on the blockchain, a copy of which is owned by each network participant. Blockchain is a diary where every N minutes all changes that have occurred in the system are recorded. Why after N minutes? So that the participants have time to exchange information about all movements of funds.

Let's look at how cryptocurrency mining occurs, that is, mining, in detail. All network participants have equal rights and do the same thing: solve mathematical problems issued by the system. One problem has many solutions, the computer will make calculations and iterate through them until it finds one that fits the requirements of the system. For example, a block whose hash has many leading zeros. When this happens, the participant who found such a solution forms a new block.

The block contains the solution to the problem and information about all transactions that occurred in the system over the last N minutes. It is attached to the end of the blockchain, and the blockchain is distributed to all other participants in the network.

Scheme of formation of transactions and blocks using the example of the Bitcoin blockchain.

The point of mining is distribution. None of the participants will be able to rewrite the transaction history and fake the blockchain. To make one block that meets all the requirements, you need N minutes of work from all miners. So calculate how long it will take one miner to generate all the blocks.

In addition, in order for a block added to the blockchain to be considered legal, it is necessary to obtain confirmation from other network participants, which consists of verifying the block key. For different cryptocurrency systems, the number of confirmations is different; for Bitcoin, for example, you need to receive 120 confirmations.

What is needed for mining

How is cryptocurrency mined? Mining takes place using a computer, a mining program and a wallet (can be located on an exchange), where coins will be accumulated. You have a computer, you can download the mining program, choose your wallet carefully so as not to run into scammers. If your funds are stolen, you will not be able to return them.

In theory everything is easy. In practice, how to mine cryptocurrency will depend on which one you choose. The fact is that the system adjusts the complexity of tasks depending on the number of participants. To put it simply, when there are too many miners, problems will be solved too quickly, so the system will automatically increase their difficulty.

The very first cryptocurrency was Bitcoin. Now it is the most popular, and the number of miners has increased greatly. Bitcoin always gives such tasks that miners mine 6 blocks per hour, 1 block every 10 minutes. Accordingly, the complexity of the tasks in the Bitcoin system is so great that the processor of a regular computer alone will not be able to cope with them, and you will not be able to earn anything.

This is roughly what Bitcoin mining farms look like now; it is obvious that the power of a home computer is not even close to comparable to them.

Now, to start making money on popular cryptocurrencies, you need other methods. You will have to invest well in powerful equipment. At a minimum, purchase several video cards. Let's look at the technical aspects in more detail.

How does mining work?

It's time to tell you how mining is organized in technically simple words. The complexity of the tasks increased gradually. At first it was possible to mine on one personal computer. Then they started mining on video cards, since they are better suited for such calculations. But the complexity grew in proportion to the popularity of the system, and soon a computer with several video cards could no longer cope.

Then farms with tens and hundreds of video cards appeared. The larger and more powerful the farm, the more it can produce, and the more profitable it is to maintain it. But the costs of its maintenance are also high; electricity costs can reach several tens of thousands of dollars per month. The most advanced farms are in Singapore, China and Iceland, and are usually located underground to save on cooling costs.

Later, special equipment for mining appeared - ASIC. These are chips designed to perform a specific task. Their power is much greater than that of a conventional computer, although the cost is much higher.

An ASIC is specifically designed for a specific hashing algorithm and is of little use for other tasks

What is better to mine

The creators of altcoins strive for maximum accessibility to mining their currencies, because accessibility leads to popularity, and popularity leads to demand for the currency and its appreciation. The mining process should be designed so that everyone, using their own computer, can replenish the network and make a profit. But which cryptocurrency should you choose for mining?

The answer to this question is simple: it is better to mine what will give you more profit. The profit will be the difference in the cost of the coins earned and the costs of equipment, electricity, Internet, etc. When choosing a cryptocurrency for mining, you should consider:

• Cryptocurrency rate - how much real money you can get from selling it;
• The number of miners in the network, which affects the complexity of the tasks;
• The complexity of the calculations is how much equipment and how much power you will need.

It will be difficult for a beginner to navigate; calculations can be carried out on a special calculator website. For example, whattomine.com.

Types of mining

You can mine in different ways. The following types of mining exist:

• Solo mining;
• Mining in pools.

In solo mining, they use their own equipment, taking all the profits for themselves. This method is effective in the early stages of crypto development, as was the case with Bitcoin. Later, the capacity of one machine became insufficient to produce a new block, and miners began to unite in pools to add up their computing power. In this case, the profit is divided among all pool participants in proportion to their shares of participation.

Not long ago, a new type of mining appeared - cloud mining.
The miner buys or rents equipment that will be located outside his home. Maintenance is usually outsourced to special services.

Advantages of cloud mining:

• You don’t have to assemble and configure the equipment, especially if you don’t understand it;
• Achieving high power that you cannot get at home;
• Possibility to mine several cryptocurrencies at once.

The disadvantages of mining in such services are the commission charged, the risks of fraud and hacker attacks. It is also alarming that, logically, having the equipment, it is more profitable for the services to mine themselves, but instead they give the cryptocurrency to others and promise rewards for attracting new clients. Be careful with cloud mining.

Pools

Pools divide rewards for blocks between participants, according to the initially agreed upon conditions.

Modern realities are such that mining popular cryptocurrency alone is possible only with expensive, powerful equipment. Now it is quite profitable to mine in pools; 99% of miners work this way.

A pool (from the English “pool”) is a server that distributes a computing task among all participants connected to it. All miners calculate it. As soon as one of them finds a solution, a block is formed, and the reward is divided equally between all participants, or in proportion to the efforts expended. What to look for when choosing a pool:

• View the characteristics of the video card to find out how much earnings a miner can expect. If the video card is built-in or old, the earnings will be small.
• Server age. There are few participants in young pools, so it is unlikely that you will be able to make money, because the strength of the pool is in the amount of computing power.
• The procedure for distribution of profits. Most pools divide the cryptocurrency they mine in proportion to the tasks being solved, and not equally, although this also happens.
• Availability of affiliate programs, the possibility of passive income from attracting new participants.
• Withdrawal of profits. In what currencies and what commission is charged.

Who pays for mining

Mining is the process of finding the correct solution to a mathematical problem generated by the system. But who will pay for it? Where does the money come from? The participants of the system agreed that a new block in the Blockchain is written by the one who finds the solution to the problem the fastest. And since he forms a new block, at the same time he writes a transaction in the block that he has been credited with cryptocurrency. It is called the “creation transaction”. Thus, the miner receives a reward for being the first.

State and mining

The state's attitude towards mining is ambiguous. In the case of electronic money, you can always find all participants in the transaction. Cryptocurrencies are anonymous. This means that they provide great opportunities for money laundering, drug trafficking, sponsoring terrorism and the circulation of illegal goods and services within the country. In addition, cryptocurrencies are not profitable for the state from a financial point of view: taxes are not paid on profits, and banks do not receive commissions for transactions. Here the state has two options:

• Prohibit and introduce penalties for the use of cryptocurrencies;
• Take control.

The first reaction of states to cryptocurrency was negative. Governments warned that the circulation of cryptocurrency is not controlled by anyone, and in case of fraud, citizens are not protected in any way. China has completely banned trading on the BTCChina cryptocurrency exchange.

Mining news reports that other countries are still considering the possibility of legalizing cryptocurrencies. The Russian government has repeatedly stated that it will lead and regulate mining in Russia. Government cryptographic currencies are also expected to appear on the market.

Expert opinions about mining are divided. Some say that cryptocurrencies are the currencies of the future that will replace money, while others believe that this is a bubble that will burst sooner or later. Like any business, mining has its pros and cons.

The advantages are that despite short-term drops, they still increase their value over time, which is what we see in the example of Bitcoin. The disadvantages are that cryptocurrencies are very unstable, they can periodically drop greatly in price, and the mining process itself is dangerous for the equipment because it wears it out.

Despite the fact that cryptocurrency appeared eight years ago, it gained the greatest popularity in the post-Soviet space at the beginning of this year. An unprecedented excitement erupted around it, and many Internet users literally rushed to study what a blockchain, pool, and Bitcoin are. They also began to learn where to start mining cryptocurrency. To date, quite a few films have already been made about this phenomenon, which are translated into Russian and are in the public domain. They can hardly be called a guide to mining (extraction) Bitcoin or any other. That is why today we will tell you about cryptocurrencies in simple words.

What is cryptocurrency?

To put it more clearly, cryptocurrency is digital banknotes that have cryptographic protection. The new unit appears in the process of solving complex mathematical algorithms and consists of one hundred million parts, each of which carries a unique cryptographic code (signature). I would like to immediately note the fact that it is impossible to counterfeit digital currency, since information about each unique cryptographic signature is copied and stored on all computers involved in the extraction (mining) of cryptocurrency.

Cryptocurrency has only digital form. It cannot be touched, put in a purse or a safe at a bank. The main advantage of such money is that it is decentralized and is not under the control of any state or institution.

The number of coins created is strictly limited and cannot be changed. Everyone can find out for sure when, for example, the last Bitcoin will be mined. Controlled emission gradually complicates and slows down the mining process, and also eliminates problematic phenomena such as inflation.

The value of digital money directly depends on demand. The more investors show interest in a particular cryptocurrency by investing a significant amount in its development, the more expensive it will be. Government banknotes are backed by gold reserves, and cryptocurrency is backed by investments.

What is cryptocurrency mining in simple words?

We have already mentioned that cryptocurrency appears as a result of solving complex mathematical algorithms. It is beyond the power of an ordinary person to effectively cope with such tasks, which is why they began to use the computing power of a computer for this purpose, and the process itself was called mining.

During cryptocurrency mining on a PC that is connected to the Internet and involved in the cryptocurrency system, information comes in the form of blocks (blockchains). Such blocks contain a huge number of algorithms that need to be processed and get the only correct solution. Each decision is a digital signature for a specific information cell located in the block. And it is also the very cryptographic protection against hacking.

The blocks themselves appear as a result of transactions using a certain type of cryptocurrency. For example, if someone paid for a purchase in an online store using Bitcoin, and your equipment is configured to mine the Bitcoin cryptocurrency, then it will immediately identify this transaction and assist in its completion, solving the same algorithms. And you will receive a reward in the form of several hundred satoshis (1 Bitcoin = 100,000,000 satoshis).

First steps in mining

We hope that we were able to explain in simple words what cryptocurrency mining is. If you decide to start mining, for example, Ethereum or Bitcoin, it will be enough to have an idea of ​​how the system works. Let's move on to the technical part and find out where to start mining cryptocurrency.

The most effective way to mine digital currency is mining using a video card. Just a few years ago, it was possible to earn several thousand bitcoins per day by using a weak video adapter and a simple processor for this purpose. However, the process of mining any popular cryptocurrency is constantly becoming more complicated. And in order to make a profit from this type of activity today, you need to think about assembling a “farm”.

"Farm"

The most profitable cryptocurrencies for mining are Bitcoin, Ethereum and Littlecoin. It is to their extraction that the main power of miners around the world is directed. Day by day it becomes more difficult to obtain these coins. In order to speed up the process, miners began to assemble “farms” that have much in common with a regular computer, but are significantly superior in performance.

To assemble the farm you need to acquire the following components:

• motherboard with the ability to connect multiple graphics adapters;
• hard drive with small capacity;
• high frequency processor;
• one stick of RAM (4-8 GB);
• 4-8 video cards with video memory from 2 GB;
• powerful power supply (from 750 W);
• risers (adapters-extensions from the video card to the motherboard);
• additional cooling;
• start button;
• frame.

Video cards for the “farm”

The Radeon RX 470 is considered the most optimal video card for cryptocurrency mining in 2017. Having impressive characteristics, they are significantly cheaper than their closest competitors from Nvidia. However, if you give preference to Radeon, you will have to think carefully about the additional cooling system, since these video adapters heat up much more than Nvidia ones. The average cost of a semi-professional “farm” working with four video cards is $2300-2700, which is quite expensive for the budget of the average Russian. However, with proper setup and continuous operation, such a “farm” will pay for itself within 6-9 months and will begin to generate income for you.

Step-by-step instructions for mining cryptocurrency

After the equipment has been purchased, secured in the frame and connected, you need to install all the necessary software. Step-by-step instructions for mining cryptocurrency are as follows:

• operating system installation;
• registering a wallet and obtaining an address;
• client installation and configuration;
• pool selection.

OS and cryptocurrency wallets

We install the operating system into our “farm”. Then we set up access to the Internet and create a special wallet for digital currency. You can create a wallet for specific coins, for example, Bitcoin. But we recommend using a universal one, in which you can store absolutely any cryptocurrency.

Among those involved in cryptocurrency mining, the following multicurrency wallet services have extremely positive reviews:

• MultiCoinWallet.
• HolyTransaction.
• NoobWallet.
• Kryptonator.
• C-cex.com.

Client program for cryptocurrency mining

Having chosen one of the services where, after registration, you will be assigned a unique account address, you need to download the client program for mining digital currency. A rating based on the popularity of a particular client, which looks like this, will help us figure out which program is better for mining cryptocurrency:

1. 50Miner. This program will not take up much space on your hard drive. With a fairly small “weight”, it has all the necessary functionality, and a simple and pleasant interface will make setting up the client simple even for a beginner.
2. BFGMiner. The most popular program in the post-Soviet space, as it has a Russian interface language. Setting up the client will not take much time, since everything is very clear. A distinctive feature from many other programs is the ability to control the cooling system. You can set optimal cooler rotation parameters.
3. CGMiner. This client is perfect for those who know perfectly well how cryptocurrency mining works and also have an understanding of the MS Dos OS. Using this utility, you can create your own pools, configure them, and also increase the performance of video cards installed in the “farm” by overclocking them. In order to use the program, you must have high-performance graphics adapters.
4. DiabloMiner. This program is popular among experienced miners who know MS Dos. To use the client, you need to equip the “farm” with a high-speed processor and powerful video cards. During the mining process, you can use the computing power of the processor and video adapters. Works with operating systems such as Mac, Linux, Windows.
5. Bitminer. The set of functionality is very similar to 50Miner. In order to start earning your first satoshi, you do not need to install the program on your computer, you just need to launch the “exe” file from the downloaded folder. A serious disadvantage of this client and 50Miner is the consumption of a large amount of RAM.

Pool selection

In our article we have already talked about cryptocurrencies. In simple words, this is earning digital currency by using the computing power of your equipment. They also said that this process is constantly becoming more complicated. In order to make mining more efficient, people join together in groups (pools).

After installing one of them, you will have the opportunity to join the work of one of the pools, of which there are already about two thousand at the moment.

Choosing the right pool can be confusing for a newbie. After all, there are both simple groups that mine exclusively one type of digital currency, and multipools that offer the opportunity to earn several cryptocurrencies at once, for example, Bitcoin and Ethereum.

Before connecting to a particular pool, it is better to spend a little time studying it. Give preference to those resources that have been working steadily for more than one year and have the largest number of positive reviews. Also pay attention to how the accumulated coins are paid out. There are about thirteen of them in total, but the most popular are the following:

• PPLNS - all miners in the pool receive a profit, the size of which directly depends on the last number of invested shares.
• PPS - the resource determines the share of each pool participant and pays it according to the contract.
• PROP - the payout amount is proportional to your share of power in a particular pool.

The best pools in 2017

From the moment the cryptocurrency attracted the attention of millions of people, pools began to appear like mushrooms after rain. However, most services, unable to withstand the competition, cease to exist. Many of them never returned the money they earned to the people who used the computing power of their PCs in their pools. In order not to lose your own money, we recommend that you use only proven and most reliable sites. The pool rating today looks like this:

1. F2Pool.
2. AntPool.
3. MTC China.
4. BW Pool.
5. Bitfury.

Cryptocurrency faucets

Not everyone has the opportunity to allocate about $3,000 from the family budget to assemble a “farm”. But this is not at all a reason to think that you will never become a miner. Today, there is a way through which cryptocurrency mining without investment becomes real. This is precisely the opportunity provided by sites that are called cryptocurrency faucets among miners.

The principle of operation of such resources is quite simple. You go to the site and perform one of the actions for which you receive a reward. For example, you may be asked to enter a captcha, play a game, assemble puzzles, or watch some video, after which a certain number of coins will be credited to your account. It may seem to you that the owner of the resource is a rich and very generous person, but this is not so. The webmaster receives income from advertising that was placed on the site. The more visitors to his resource per day, the more the advertiser will pay for banner space.

You won’t be able to earn a lot on such “faucets”, but the collected funds can be reinvested in the purchase of capacity on resources offering cloud mining services. A similar scheme may be useful to people who do not know where to start mining cryptocurrency.

Top cryptocurrency faucets

In order not to waste time, we suggest you familiarize yourself with the list of the most reliable and generous “faucets”:

1. Cryptoblox.
2. Getmyfaucet.
3. Cryptospout.

Today there are a lot of similar resources, but most of them are insolvent.

Any user is concerned about the security of his personal computer and tries to ensure its maximum protection. With the growing popularity of Bitcoin and other digital coins a large number appeared malware. And we are talking, in particular, about virus miner programs that, without the knowledge of the owner, mine cryptocurrency. Given the scale of this problem, both beginners and more experienced community members should know what a miner virus is and how to remove it from a computer.

Despite the protracted crisis and the fall in the value of top crypto coins, the relevance of their mining remains, which is proven by the popularity. In this case, you should pay special attention to security and protection against virus software, and also know how to remove it as quickly as possible when detected.

What is a miner virus and how can you get infected with it?

The record popularity of blockchain technology and the active expansion of the areas of application of digital money, as well as their attractiveness as an investment object, could not go unnoticed by scammers. Everyone should know what a miner virus is and how to find a similar program on a PC. As practice shows, absolutely any user can become a victim of hidden mining, including those who have never heard anything about cryptocurrencies.

Mining virtual coins requires appropriate computing power. Based on this, you can determine a possible infection with a virus miner by frequent freezing of your PC. At the same time, the program, using the equipment resource, brings profit not to its owner, who somehow managed to download it, but to its creator. It is quite easy to detect a virus, but you need to know how to completely remove it.

The first step is to understand how malware can get onto your computer. Infection by hidden miners is similar to infection any other viruses, which appear on PCs and laptops in the following cases:

• when visiting dubious sites;
• in the process of downloading unverified files;
• via Skype and other instant messengers;
• through social networks;
• via email.

In the vast majority of cases, searching for malicious utilities immediately after they enter the system does not produce results. This is explained by the fact that the virus miner requires a certain time to master the disk space and resources of the computer. And after activation, it can sometimes be quite difficult to get rid of a malicious program. Since a Trojan can be picked up anywhere, there is no clear list of resources that should be avoided.

Precautions to Protect Against Hidden Miners

After you have managed to understand what a miner virus is on Windows, you should understand exactly how you can protect your computer or laptop as much as possible from infection by such Trojans. The popularity of making money on cryptocurrency, including the opportunity, continues to grow. It is for this reason that you need to know what needs to be done to minimize the risks of becoming a victim of attackers.

• install a reliable antivirus and monitor its timely updating;
• create system restore points to enable so-called rollbacks;
• avoid visiting dubious and suspicious sites;
• track the download and installation process of any software;
• If possible, do not store important logins and passwords on your PC.

The key to maximum safety is careful control of actions user related to the operation of equipment and storage of personal data. Otherwise, you may encounter serious problems.

Video: How to find and remove hidden miner virus on your Windows computer

It has become one of the most popular and discussed topics of the last year. Many people invest in this industry and continue to earn good income.

Of course, this industry is not without criminals looking for easy money. Hidden Bitcoin miners have begun to be actively used among hackers. This is the name for programs that are installed on a computer secretly from the user and use computer resources to mine cryptocurrency in the background. In this article we will talk about how to identify hidden mining, how to get rid of it and what it is all about.

What is hidden cryptocurrency mining?

Hidden mining is the process of mining cryptocurrency by an attacker using the computer of an unsuspecting victim. The most commonly used hidden mining is Monero or ZCash. Applications are installed specifically for mining forks, because it is more efficient to mine some smaller coin with one core than Bitcoin with the entire power of a PC. Moreover, such viruses exist even for Android. There have also been cases where hackers used NiceHash and MinerGate. This often happens as a result of hacking, or some kind of malicious program entering the computer, be it a mining bot or a botnet.

Often, the developers of such viruses do not limit themselves to mining on the CPU or on a video card and supplement their programs with various spy functions. For example, a virus can steal wallet files for various currencies, login data for social networks, or bank card data. After such attacks, the computer becomes extremely vulnerable and unsafe to use.

It should be noted that searching for a botnet is sometimes too complicated and it is impossible to detect it with the naked eye. This is due to the fact that not all viruses put a high load on the processor. Some of them use very little power for better camouflage. This is especially often used on high-performance systems. In addition, there is also hidden mining in the browser. However, modern browsers can recognize this and always report that this site is trying to use your browser to mine cryptocurrency.

How it works?

The operating algorithm of such viruses is very simple. The program launches the miner covertly and connects to the mining pool where cryptocurrencies are mined. These actions significantly load the processor. The main task of the software is to receive money for the unauthorized use of other people's computing power. The scammer receives the cryptocurrency earned by the victims directly to his wallet. Pools in this scheme can be considered an ideal way to create such botnets, because most pools support an unlimited number of users connected to one address and their membership does not need to be proven to anyone. And if you have a botnet of hundreds of computers, you can easily use even the largest pools with a high minimum withdrawal amount of earned funds.

How does infection occur?

Security experts identify several main causes of botnet infections. Typically, such viruses enter a computer for the following reasons:

• Downloading and running files from the Internet. Hackers find many ways to distribute their programs and embed them in distributions on dubious sites.
• Physical contact with an infected device. You can also “pick up” such software using other people’s flash drives and other devices for storing and transmitting information.
• Unauthorized remote access. Classic remote hacking is also used for infection to this day.

You can find a lot of news online about how people tried to use hidden mining at work, infecting entire offices. There are also known cases of attempts to distribute mining malware through Telegram.

Why does the miner work in stealth mode?

Another question is how such a virus manages to remain undetected and how to determine its presence. The whole secret is that it gets onto the computer along with some files and documents, and its installation occurs in silent mode. The cryptocurrency mining process is hidden under one of the Windows services or is not displayed at all. Another interesting feature of the modern miner is that its operation stops when the load increases. This is done to reduce inhibition and, accordingly, the risk of being detected. It may seem that hackers are losing a significant profit, but this approach is safer for them if they have a large network of hacked PCs.

In some cases, the system even hides the source code of the virus, which automatically restores it by running bat on the device if it is deleted. In such situations, the treatment process can be very delayed and require much more serious measures.

How to find a hidden miner on your computer

If you suspect that there is a botnet on your device, you can easily check for hidden mining using the following steps:

• Determine how the device operates under standard load, such as running regular programs or a browser. It is important that everything works as usual.
• Check the stability of the system using a computer game and clarifying hardware indicators. Productivity should not decrease.
• Run applications like AIDA64 to check the video card and central processor, depending on whether programs are turned on and off in the background.
• Draw conclusions based on the data received and take action.

Some virus miners stop working before the device user opens the task manager. This allows you to bring the indicators back to normal and get rid of unnecessary suspicions. Sometimes stealth miners can even turn off the task manager on their own after a few minutes of its operation. Accordingly, if you remember that you opened an application, but after some time you do not see its window, then you should think about the possibility of infection. It can be detected by powerful programs for monitoring the state of the computer. These include AnVir Task Manager, which will allow you to find all suspicious processes in the operating system. High-quality diagnostics is always possible, but sometimes it requires large costs and resources.

How to remove a miner virus

Antivirus software will help you find the miner virus using a deep scan, but you can't count on it to also help remove the detected infection. In most cases, you have to deal with this manually and you will need to remove the malicious script yourself. It should be noted that traces of hacker software may still remain on the system, and a much better option would be to back up all data and reinstall the operating system.

Most often, infection occurs due to downloading pirated content, for example, games from torrent trackers. If you remember doing something similar, then it won’t be difficult for you to find the possible cause on your own. The main thing is to determine in what time period you started having problems with your computer. The first thing you need to do is remove all suspicious applications and only then can you start fighting the virus itself.

If you are lucky, you will find a simple miner on your device, which will not be difficult to get rid of. You just need to open the task manager and select all the activity that is suspicious to you. To do this, you need to go to the start menu and select the processes section. You can also simply call up the task manager using the standard keyboard shortcut control+alt+delivery. If you find any task that uses more than 20 percent of the CPU power, then most likely the miner has already been found. All that remains for you is to complete the process.

However, it should be noted that such a procedure is often not enough. Recently, attackers have learned to hide their products much better and it has become more difficult to find a miner in the system. As noted above, some modern bots read the opening of the task manager and make the treatment process much more difficult. But even here you can get out of the situation if you follow the recommended action plan in such cases.

First, you should check your device for viruses and restart your computer if any are found. Then you need to switch to BIOS mode to manage the hardware without using the operating system. To enter the BIOS, the F8 or Del buttons are usually used. This may vary depending on the manufacturer. Next, open the Advanced Boot Options section.

It should be noted that you will not be able to open this menu if you have Windows 10 and you reboot. In this case, press Win+R and enter the MSConfig command in the window that appears in front of you. Now you need to select the system configuration section and select the desired mode in the boot menu. Now we just reboot the system on the PC.

The advanced boot settings menu contains many items, but in this case we need Safe Mode w\ Networking. Now you just need to log in to the OS using your account and open the browser to access the Internet. All that remains is to download any anti-spyware software of your choice. This is what we will use to treat the hidden miner.

Almost all utilities of this kind will remove detected threats automatically. In addition, entries from the Windows registry will also be deleted and the settings of some applications will be adjusted.

If you don’t know which software to choose for this, then experts recommend Malwarebytes Anti-Malware to combat spyware. You can also use Doctor Web products to combat hidden mining. The most effective program for removing miners on the company’s website is CureIT. Reviews indicate that after her work there are no repeated complaints.

Prevention of hidden mining

It should be understood that complete security on the Internet cannot be guaranteed these days. With each update of the anti-virus databases, new viruses appear. However, thoughtful actions will still reduce the risk of infection of the device. To do this, you need to use only trusted sites, and do not ignore warnings from anti-virus software, including those built into the browser. You should also periodically activate the check for prevention. It is also recommended to limit or even stop using pirated content, as it is often accompanied by viruses.

Legality of hidden mining

Mining in general, and especially its niche branches, is still an unexplored area that does not have a clear definition in the legal field. However, this does not mean that if there is no article for hidden mining, then responsibility for it will not follow. Installing software on other people's computers secretly from their owners, infiltrating networks - all this is enough to initiate a criminal case. It doesn’t matter at all for what purpose this happened. It’s better not to break the law and earn cryptocurrency honestly. In addition, stealth mining will not bring significant income and you will not earn as much as you can earn with more honest transactions with digital currency.

In conclusion, we can say that the emergence of new cyber threats associated with cryptocurrency is a very expected result of the popularization of this technology. However, the field of information security also does not stand still, and users can easily protect themselves from malicious software and scan their computer to detect infection in the early stages. It should also be noted that the constantly improving security algorithms in web browsers are already capable of blocking hidden mining and preventing malicious software from being downloaded.

In this article I will tell you what it is miner, how to identify it, and also explain how to remove the miner from your PC. If you notice that your computer makes a lot of noise and heats up when idle, not the most demanding games begin to slow down terribly, and in the task manager some process loads the system to the maximum - then it is quite possible that a program under called "miner".

The term " miner"(English miner) - translated from English as "miner", and the process of "mining" is usually called the development of deposits of any natural resources. If we take our “digital” case, then such a “miner” (miner) will be a program for mining - solving certain mathematical problems, for which there is a reward in the form of several units of digital cryptocurrency (bitcoins). Read more about this process and how to make money from it (including without investments) in our next article.

The mining process is as follows. All existing transfers in bitcoins are recorded in the general transaction log and transmitted to miners, who must select from all possible combinations one hash that is suitable for all new transactions, as well as the secret key (for solving the key code, the miner receives a reward of 25 bitcoins). Many miners try to simultaneously guess the hash and receive a reward, but in most cases this is achieved by the most “resourceful” miners. Once the cache is guessed, the transaction block is closed and miners begin solving the new hash.

When mining, the power of the graphics card's graphics processor, which is more suitable for solving mining problems, is usually used. Moreover, if earlier an ordinary home PC was enough for mining, then later the power of top-end video cards began to be used for this process, and now special devices (ASICs) have been created for mining, characterized by high hash calculation speeds and low power consumption.

A video about this mining can be seen on the video:

How to detect and find a miner

It’s one thing if you have a computer with a powerful video card, you decide to try to earn a couple of tens (hundreds) of rubles, and you independently installed a program for yourself - a miner. Another thing is that you didn’t do anything like that, but you noticed that your computer began to make a lot of noise and freeze, the video card got very hot, during idle time the PC resources were consumed by 80-100%, and even the most mediocre games suddenly began to slow down a lot. These indicators show that this is the Miner installed on your PC. The miner can also be identified in the task manager by the processes btc.exe and miner.exe, although, in most cases, the miner is hidden under the name of some important system file.

Another sign of the presence of a miner on a computer is electricity consumption. When mining, a computer consumes significantly more energy, and the laptop battery runs out in just a few minutes.

Usually, most miners end up on a computer as part of some kind of virus, which, in addition to its malicious work, installs the miner into the system. The latter, after its installation, immediately begins to earn money for its owner, using the power of the infected user’s system. Now the user not only pays for the miner’s Internet traffic, but also for the computer’s increased consumption of electricity, and all the bitcoins earned by the miner will go to the virtual criminal’s wallet.

How to remove a miner

First, check the list of programs installed on your computer (in the list of uninstalling or changing programs). If you see names related to mining or Bitcoin among the programs, delete the program data and restart your computer.

In most cases, antivirus programs do not notice the miner, since its functionality does not allow the miner to be identified as a virus. However, there are programs that have proven themselves well in the fight against malignant miners - this is Dr. Web CureIt!, SpyHunter, Malwarebytes Anti-Malware. Install one of these antivirus programs, conduct a full analysis of the contents of the computer, in most cases the antivirus will detect the miner and delete it.

If these methods do not help, then try removing the miner yourself:

1. To do this, in the task manager, look at which process loads the computer to the maximum, right-click on it and click “Open file storage location.”
2. The system will open to you the directory where this file is stored.
3. Now you need to end this process in the task manager, and then delete this file in the previously opened directory.
4. Before deleting, I advise you to search through search engines to find out what kind of process it is and where the file for this process should be located.
5. If it's a system file and it's in its "home" directory, then it's most likely not a miner.
6. You can also use the functionality of the CCleaner application, which allows you to effectively remove unnecessary programs and processes, including their entries in the operating system registry.

Well, if nothing helps at all, then we can recommend a complete reinstallation of the operating system. Of course, this is an extreme step, but it can also be taken in order to completely get rid of the unwanted miner.

Conclusion

What is Miner? In most cases, the miner ends up on the computer bundled with some kind of malicious program and begins to function without user intervention. The resources of such a PC are directed to mining, and the user begins to experience significant slowdowns and frequent freezes of his system. To remove a miner, it is enough to trace its location and delete it; the functionality of the anti-virus programs mentioned above will also help here. Well, those who want to try to earn a little money can always download a miner and start using its capabilities, but keep in mind that the resource capabilities of your PC must be at their best. Although, trying is not torture.
