Recently, I’ve noticed that many people's computers are inexplicably slowing down, and I realized that most people don’t even know they might be infected with hidden mining malware. These malicious programs secretly use your computer to mine cryptocurrencies in the background, and sometimes antivirus software can’t even detect them.

Let me start with the most obvious symptoms. If you notice your graphics card running wildly, CPU usage soaring above 60%, your computer running noticeably slower, or inexplicably consuming a large amount of network traffic, there’s a high chance you’ve been infected. Laptops are especially prone to this, and sometimes they can even crash directly.

Mining viruses generally fall into two types. One is a file downloaded directly to your computer that automatically starts every time you boot up. The other is more covert; it exists in the form of web scripts that activate when you visit infected websites, and antivirus software often can’t detect them.

Regarding removing mining viruses, I think the most important step is to first confirm that you are actually infected. Open Task Manager to check if there are any strange processes running, such as “asikadl.exe” or other unfamiliar names. You can also use free tools like GPU-Z to check your graphics card load.

The removal process I recommend is as follows. First, run a full system scan with your antivirus software, then use CCleaner to clean junk files. If problems persist, you’ll need to manually check the registry. Press Win+R to open regedit, then use Ctrl+F to search for suspicious process names. Once found, delete them directly and then restart your computer.

Deeper removal of mining malware can be done through the Task Scheduler. In Windows 10, type taskschd.msc to open it, and check if there are any unfamiliar automatic tasks in the “Task Scheduler Library.” Pay attention to the “Triggers” and “Actions” tabs; if you find anything suspicious, right-click to disable or delete them. Sometimes, new mining programs add themselves to the trusted list, and in such cases, you can use AnVir Task Manager for in-depth inspection.

If these methods don’t work, you might need to use professional antivirus tools like Dr.Web for a deep scan. It’s best to back up your system before cleaning, just in case.

Long-term protection is key. Regularly update your antivirus software and firewall, and check reviews and information before downloading programs. Most importantly, don’t run programs as an administrator unless necessary, as this makes it easier for mining malware to get in and harder to remove. Set strong passwords, disable remote access, and turn off JavaScript in your browser settings—these can significantly reduce your risk. Chrome now has built-in mining detection features that can be enabled in privacy and security settings.

Honestly, if you follow these protective measures, you generally won’t have to worry too much about mining malware. Computer security is about proactive defense; waiting until a problem occurs to clean the malware is passive.
