Hello, i think i have a virus on my PC. So about my problem, when i wasn't doing anything on my PC (was on my phone or sth) I noticed that my fans are pretty loud for an idle PC, so i wanted to check it what's going on by oppening Task Manager, but then it went quiet so i thought it was something temporary and normal. But then it happend again so i checked my CPU usage in diffrent app. I noticed that 3 Threads are used in 100%, but whenever i open Task Manager its going down to 0-5%. I scanned my PC with Malwarebytes, and Adwcleaner and they can't find anything, but it for me it looks like some kind of Bitcoin Trojan or something. I failed to find on my own what makes it happend. Also this "virus" does not activate immediately after closing Task Manager but it takes some time. Please help me resove this problem.
