I was stupid enough to click a link from a complete stranger and now my computer is bugged. It seems the only serious thing it does is disable my anit-virus software. I've tried with AVG, Microsoft Security Essentials and Kaspersky PURE, but none of them can beat the little bastard. Can anybody give me any advice? Perhaps some nice anti-virus software? Or is formatting the only option? I wouldn't want that, since I don't have the disk with my system.
