I recently encountered a problem that many people are unaware of — miner viruses. This is really unpleasant stuff that can seriously damage the life of a PC owner. I want to share how to remove a miner from your PC and how to determine if your computer is infected.

First, let’s understand what’s really happening. A malicious miner program is essentially a Trojan that infiltrates the Windows system and starts using your hardware’s power to mine cryptocurrency. And it happens unnoticed, in the background. There are two main types: browser-based cryptojacking, embedded directly into web pages, and the classic virus file that installs on the disk.

Why is this dangerous? First, if a Trojan is sitting in your system, your passwords and data are at risk. But if it’s a miner, it can also damage your hardware. The graphics card and CPU run at maximum capacity, the graphics card starts overheating and humming like a turbine, and a laptop can even fail after a few hours of background mining. Plus, electricity consumption skyrockets.

How to tell if you’re infected? Here’s what to look out for. If your GPU makes strange noises and is hot — check with GPU-Z. If your PC slows down, open Task Manager and look at CPU load. If it’s 60% or higher during normal use — a bad sign. Also monitor RAM usage, internet speed, and strange browser behavior. Sometimes, you’ll see processes with suspicious names like asikadl.exe in the Task Manager.

Now, the main question — how to remove a miner from your PC. First step: run your antivirus and perform a full scan. After that, it’s advisable to run Ccleaner or an equivalent tool to clean out all the junk left by the virus. Then reboot your system.

But some clever miners add themselves to trusted programs, and antivirus software doesn’t detect them. In that case, manual checking is needed. Open the registry: Win+R, type regedit, OK. Use Ctrl+F to search for suspicious task names. If you find anything strange — delete it.

Another method is through the Task Scheduler. Win+R, taskschd.msc. Open the Task Scheduler library and see which processes are set to run automatically at startup. If you see anything suspicious — disable and then delete it. Check the Triggers and Actions tabs.

For a deeper scan, use Dr. Web or AnVir Task Manager. They detect more complex viruses. Before deleting, it’s best to create a system backup just in case.

To prevent future infections, you need proactive measures. Install and regularly update antivirus with a firewall. Before downloading programs, check their information. Scan all files with your antivirus. Work online with protection enabled. Add dangerous sites to your hosts file — there are ready-made lists on GitHub. Don’t run programs as administrator unless necessary. Use secpol.msc to create policies for only trusted software. Set a strong password on your router and disable remote access. Set a password on Windows itself. Avoid visiting sites without SSL certificates — look for https. Block JavaScript in your browser — this prevents malicious scripts from running, though some sites may not work properly. In Chrome, enable mining protection in privacy settings. Install AdBlock or uBlock to filter out ad scripts.

In short, how to remove a miner from your PC is a combo of antivirus, manual registry and task scheduler checks, plus overall prevention. Don’t ignore early signs, because the virus will only harm your hardware. It’s better to spend an hour checking than to later have to replace your graphics card or motherboard.
