Seems to be a bit of an upsurge in miner viruses getting into people’s computers lately.
A crypto coin miner virus finds its way onto your computer (PC, Mac, or Andriod devices), quite often via a web browser accessing an infected website. It then uses your computer (without your knowledge) to “mine” crypto coins. For a good explanation of crypto coins and “mining” check out https://en.wikipedia.org/wiki/Cryptocurrency
Some of these viruses are exceptionally good at getting into your system – some will turn off your anti-virus software, or even trick the system into thinking that the anti-virus software is still working. The virus quite often “pretends” to be a legitimate file – often using Microsoft file names.
Generally, the only way that the user will be aware of the virus is that their device runs more slowly or seems to be highly active on the broadband connection even when the user is doing nothing. In worst cases they can overheat the CPU or GPU and damage your system. If you have a limited or “capped” broadband connection – you may find that you are unusually running out of bandwidth every month.
There are many different viruses around and each can need different ways of removal. If you are “tech savvy” ensure that your anti-virus is running correctly and has been recently updated. You can check in Task Manager in Windows – right click in the bottom task bar, and in the menu click on Task Manager. This will display a list of all programs etc currently running on your PC. Click on the CPU column heading which will sort the highest using program to the top. If you do not recognise the program and its CPU usage is high – it could be a miner virus. You could then Google this file or program.
You will then need to use a reputable malware removal program, such as Malwarebytes, or Spyhunter 5
As always – if you have any concerns or questions – please let me know
