This article can help you to remove Virus. The step by step removal works for every version of Microsoft Windows.

It seems that everybody’s mining cyber-coins nowadays. Did you know that the websites can mine them too. Special scrips, embedded on their website allow the website owners to turn their incoming web traffic into coins. This new “drive-by-mining” technology is supposed to be an alternative to the classic online adverts. provides such a drive-by-mining script. It is not a virus. When you visit a page that uses it, you should be notified about its presence and functions. If you are not, however, then you can consider the script illegal. Without your permission, the mining script should not start. Unfortunately, that is not always the case. Many websites use the technology to mine in the background. They steal their visitors’ resources. Basically, when you visit such a website, your computer is forced to perform complicated accounting operations for a coin platform. In exchange, the owners of the site get paid with fractions of the coin. The longer you stay on their website, the bigger the profit. Yet, you might not want to allow them to use your computer resources. The mining process requires a lot of CPU and GPU power. In theory, the “virus” should use just 20% of your CPU which is supposed to limit the side effects. Yet, these 20% are still a lot. You might experience system unresponsiveness, crashes, unstable Internet connection, and various errors. Your anti-virus app may also display warnings and cause inconveniences.


How did I get infected with?

The script is not a virus. It doesn’t travel the web. The script executes in when you open a website that hosts it. Once you close the page, the script should also stop. However, you might have noticed that your device underperforms even if you are not using your browser. If that is the case, you should scan your OS for malware. All sorts of nasty parasites have similar symptoms. They usually arrive hidden in software bundles, spam emails, corrupted links, and fake updates. The Internet is a dangerous place. You can never know where an infection might strike from. So, do not be negligent. Only you can keep your device protected. Don’t visit suspicious websites. Do not be negligent, always read the terms and conditions/EULA. If you don’t have the time to do so, use an online EULA analyzer to scan the text. If you detect anything out of the ordinary, exit the suspicious website immediately. Stay away from torrents and illegal platforms. And, of course, be very careful with your inbox. The good old spam emails are still the number one virus distribution method. Always choose caution over carelessness!

Why is this dangerous?

The “virus” should not be underestimated. It forces your computer to work for it. The script takes everything your device has to offer and leaves very little for you. The coin mining process requires a lot of processing power. It uses what it needs and leaves your computer slow and unresponsive. Your comfort, however, is not the problem here. The mining process wears out your hardware. Your CPU is forced to work at high temperatures. And as you know, the heat is bad for your device. You may end up with irreversible hardware damage. Speaking of heat, let’s not forget that it was originality electricity. Your machine, after all, runs on it. The more busy your device is, the more electricity it consumes. “virus” keeps your machine very busy. The coin mining process is profitable only if you don’t use your own resource. The crooks are using yours. You paid for the hardware, you will also pay for the electricity. Bear in mind that even if you want to support a website you like, the drive-by-mining is not a good option. You can never be sure who is at the other end. It might be the owners of the page, yet, it might also be some cyber-criminal who hacked your favorite page. Make sure you know where your money goes. Don’t tolerate unethical strategies.
