JS:Miner-c – malware which eats your CPU power to mine cryptocurrency illegally

JSMiner-C
JS:Miner-c - a trojan which infiltrates the system without the user's permission.

JS:Miner-c is a malicious application that falls into the category of a trojan horse. It infiltrates the system unnoticed and uses targeted system's resources to illegally mine cryptocurrencies such as Bitcoin and Monero. Notice, all actions are done without the user's permission. The computer will face slowdowns as JS:Miner-c trojan will use more than 70% of the CPU power which might shorten its lasting. Such activity has only one purpose – to bring income for cybercriminals.

Name JS:Miner-c
Type Trojan 
Purpose To mine cryptocurrency on targeted computers without the user's permission
Symptoms High CPU usage, programs launch slowly, no ability to fastly minimize/maximize windows
Danger Medium. Can result in hardware wear and tear, as well as increased electric bills
Elimination Use Reimage

If you got your computer infected by JS:Miner-c, you may notice these symptoms:

  • CPU usage has increased;
  • Software does not run as quickly as it should;
  • You are not able to maximize and minimize various windows fast anymore;
  • Your computer is working slower than before and facing various struggles.

Cryptocurrency mining is not illegal if it is done with permission – it is an excellent alternative for website developers, so they can use some of the visitors' CPU power instead of displaying annoying advertisements. Nevertheless, the site owner needs to let users know that such activity is taking place. Otherwise, such monetizing method becomes an illegal act. Additionally, crooks that inject JS:Miner-c to secretly abuse victims' computers are criminals.

JSMiner-C
JS:Miner-c is malware which might cause the installation of various PUPS.

Nevertheless, JS:Miner-c has other intruding features. It might lead you to questionable websites and cause a PUP infiltration such as browser hijackers, ad-supported programs, and other Trojan horses. Your computer resources such as the CPU usage will be used highly. To avoid these dangerous actions, you need to remove JS:Miner-c from your operating system. We recommend using Reimage for this process.

You should take care of the JS:Miner-c removal as soon as you spot any of the symptoms. Do not hesitate as your computer will become slower with each passing day, and can eventually lead to destruction. As soon as you delete JS:Miner-c from your machine, you will be able to run programs as usual. 

Keep your computer protected from trojans and other malware

Trojans are especially dangerous kind of malware because it can sneak in unnoticed, and can remain in the system for a long time before it is detected. That is another reason to obtain and install reputable security software on your computer. Nevertheless, it might still be not enough, because detection of the virus depends on a database of the AV engine. In other words, somebody has to get infected for the researchers to start marking it as malicious and giving it a name.

Therefore, the best thing you can do is not to get infected in the first place. It is true that it is still not 100%, but the knowledge of malware distribution can definitely reduce the chances of the virus infiltration.

The first thing you should remember is to stay away from spam emails. These malicious letters can look legitimate, and carry an attachment or a link which, when clicked, would immediately distribute malware's payload. Thus, learn to recognize phishing emails and don't get scammed.

Another popular spot for malware is file-sharing and torrent sites. Do not download codecs, missing system files, illegal software, cracks and similar onto your PC, because any kind of executable can carry a virus inside. What is more, porn, online casinos, free online gaming and other dubious sites should be avoided as well, as they are known as being less secure and are easily hacked by cybercriminals.
