What is CPU Miner
CPU Miner is a virus that belongs to the adware subclass. This virus is automatically installed on your computer, after which it changes the start page of your browser and installs all kinds of advertising ads into it. Due to the presence of malware in the system registry, getting rid of CPU Miner is a difficult task. In most cases, this virus enters the system when downloading free software, all kinds of torrents, unofficial patches for computer games and other content from unreliable sites. The creators of these portals begin monetizing the content by wrapping the virus in a download file. A downloader is a special software that transfers downloaded content to you, while at the same time installing viruses that change the home page, install ads in the browser, install various redirects, and the like. CPU Miner belongs to the list of such programs.

What is CPU mining?
Cryptocurrency mining is the process of releasing coins from the project network. In order to obtain digital assets, you need computing equipment. The devices are connected to the cryptocurrency network and they begin to process various tasks. In particular, the computing power of machines is needed in order to conduct transactions with coins and record information about them in the blockchain.
Among the computing equipment that is often used for mining cryptocurrencies are video cards, ASICs (machines designed specifically for mining coins) and processors (CPUs).
CPU mining is the least profitable option for making money from coin mining. Moreover, in order to start mining on a processor, one computer is enough. Accordingly, the miner can save on the purchase of equipment for work.
How to remove CPU Miner
Cleaning up CPU Miner involves getting rid of all browser add-ons with the name CPU Miner, all registry keys that are associated with this virus, and every virus file on the computer. Typically, removing an add-on in browsers with the name CPU Miner has an effect either before restarting the browser or before rebooting the system. The virus program repairs itself. You can remove all extensions and add-ons in browsers, remove it using the Add or Remove Programs function, find the program on your computer and get rid of them yourself. The work will be useless. However, only experienced computer users with extensive experience can clean the registry. If you make any mistake in the registry, you will need to reinstall the OS or it will be able to work, but errors will appear on an ongoing basis. Because of this, we advise only fairly experienced users to clean the registry themselves; moreover, you clean the registry at your own peril and risk. For this reason, we recommend automatic removal of CPU Miner using a utility called Spyhunter 4, created by Enigma software.

Why CPU mining is still relevant
Mining on a processor is much less energy intensive than mining coins on a GPU or using ASICs . This is largely why many developers deliberately create cryptocurrencies tailored for the CPU.
There is a theory according to which the market capture by GPU and ASIC miners makes the crypto industry centralized (through the concentration in the hands of a group of individuals of a large amount of hashrate in coin networks).
The work of miners through CPUs scattered around the world , according to a number of participants in the crypto community, on the contrary, helps maintain a high level of decentralization of the crypto industry .
Step-by-step instructions for manually removing CPU Miner
We repeat that you carry out this operation at your own peril and risk. Each PC has its own operating system with many differences. Of course, the main registry keys, files, folders are the same, but if, for example, your computer has some program in which the registry key contains the word CPU Miner (a fairly common case), and this program uses certain system services - in most cases after removing them, your system will no longer start because the system registry has become corrupted.
Step 1. Make a restore point.
Be sure to create a restore point. You will not be able to restore the system if a restore point is not created.
- Right-click on “Computer”, then select “Properties”.
- The “System Protection” button, then the last button at the bottom right “Create”.
- enter a name for the recovery point, and then click “Create”.
Step 2. Remove the program from the PC.
- You need to log into “My Computer”, then click on “Delete or change a program” (this menu is located at the top).
- We look for “CPU Miner” in the drop-down list and click delete on the right.
Step 3: Remove browser add-ons and extensions.
Each browser has its own button to open a list of extensions.
Google chrome
Go to the menu, then to Settings, then to Extensions (the menu button is at the top right). In extensions, look for CPU Miner and click Delete.
Internet explorer
Go to Tools - Configure add-ons. Find CPU Miner and remove it.
Mozilla Firefox
Go to the menu (top right), click Add-ons, look for CPU Miner and click Delete
Step 4. Clear the system registry from CPU Miner.
- Press win+R, a line will appear, write regedit in it, the registry will open.
- Then we look for malware. Press Ctrl+F, type CPU Miner and press enter.
- The found key will appear - delete it.
- We search further using the F3 key. Thus, we delete everything that the search gave us, then a message will be displayed that nothing could be found.
We reboot the computer. After reboot, if the system failed to boot:
- When the screen is black, press f8 and f9 as quickly as possible to enter safe mode.
- in the menu, select safe mode and after loading it, we restore the system Start - Accessories - System Tools - System Restore - select the previously created restore point and begin restoring the system.
- Sometimes it happens that safe mode does not start. In this case, you need to select line No. 1 in the menu, then restore the system based on the prompts.
When there is only one virus, these actions may be enough. But viruses are often grouped together: they are able to restore one another if one of them survives. For example, by the time this article was written, the CPU Miner virus had a large number of modifications. We recommend getting rid of swetim automatically with the spyhunter 4 program. Thanks to this utility, you will cure your computer of this virus, as well as others that you may not know about. In addition, the CPU Miner virus, penetrating onto a computer, can collect many similar viruses.
Types of mining on a processor
Mining on a processor can be different. It all depends on the approach to work. Let's look at two main answers to the question of how to mine on a processor.
Solo mining on CPU
Cryptocurrency mining in a solo format implies independent mining, without combining your computing power with other market participants.
Mining on CPU in a pool
A pool is a platform for uniting miners. The scheme works as follows:
- Miners combine the computing power of their devices, thereby increasing mining profits.
- After receiving the reward, the coins are distributed among all pool participants.
Many members of the crypto community consider this approach to work to be more profitable than solo mining.
Interesting! It is not always necessary to have your own equipment for solo mining or working in a pool. Computing power can be rented. This approach to work is called cloud mining. Find out more about him from our material.

Is it worth removing such viruses?
Naturally, you can use the computer with annoying banners, this is not critical. However, the virus can open the way for other viruses from the manufacturer. Moreover, the viruses themselves are updated and improved. Thus, the malicious program not only displays ads, but can also easily store confidential data: credit cards, social networks, email passwords and other information that you type on a computer with a virus. This is certainly much more serious than browser ads.
Setting up CPUMINER-OPT
- cpuminer.exe - Specify the name of the program to be launched. For cpuminer-opt it will be different - cpuminer-avx2.exe
- -o stratum+tcp://eu.vrm.mining-pool.ovh — Specify the pool address
- :3032 — Put a colon and indicate the port from the pool
- Weblogin - After the -u , indicate either the login on the pool, if registration is needed there, or the address of your wallet
- WorkerName — Specify the name of the worker (farm name)
- -p WorkerPassword — Specify the password. Put X if there is no password
Miner configuration
You need to go to the web page of the selected pool and read their documentation. There should be an address and port that should be used to connect your miner. For example, pool.xmr.pt:3333.
Next, using the text editor you are using, you need to open the config.json file that you copied or extracted earlier. You should scroll down to the line that says donate.v2.xmrig.com:3333 and change the text in quotes to your pool address. The line below should contain YOUR_WALLET_ADDRESS. You should change this text to your actual wallet address.
After making these changes, the resulting configuration should look something like this:
{ // […] “pools”: [ { “url”: “pool.xmr.pt:3333”, “user”: “43YjW8SZov...” } ], // […] }
How to choose the best CPU for mining?
To organize mining on a processor and select suitable equipment, you should pay attention to a number of technical characteristics. We invite you to talk about them in more detail.
Cores
As a rule, the more cores a processor has, the better. A high score means that the CPU can multitask efficiently. The choice should start with processors with 8 cores.
Streams
CPU multithreading support improves processor performance. Also, as in the case of cores, the more threads a device has, the better.
Speed
Effective mining requires high hashrates. As a rule, the more GHz the CPU has, the better the level and the more competitive the miner’s equipment becomes.
Important! Experienced miners do not recommend using laptops for mining cryptocurrencies. For mining, in their opinion, stationary computers with powerful power supplies are best suited.
conclusions
CPU mining is one of the least profitable ways to make money from cryptocurrency mining. It can be considered solely as an additional source of income.
At the same time, CPU mining is much simpler than mining cryptocurrencies on a GPU or using ASICs. You can learn more about how to start mining cryptocurrency in 2022 from our material.
