I used to be able to play games at 60+ fps. One day later I can't run anything without lagging hardcore. No game will let me play fast. I want to think it's a virus or something but I ran a few AVG scans only a couple viruses, they were removed and still no difference. Please help, thanks :)

EDIT: The entire system is slow as heck.
