So I have been experimenting a lot with my new PC and have been downloading some stuff I shouldn't have and have downloaded the wrong things at times. I did a scan and both malwarebytes and avast picked up a virus. It said the Severity was high and that it was a Rootkit Modification. I did what both things said and removed it. But every once in awhile something pops up that says "Malwarebytes Has Successfully Blocked Access To Malicious IP". I am also noticing that some games don't play right and crash sometimes. I'm scared I might have a virus and was wondering what to do. I would just Format my hard drive but I can't because it says "It contains the version of Windows you are using". What do I do? Also keep in mind that I don't know much about this kind of stuff.
