So recently I've downloaded this trainer for an old game and now it's infected my system. It uses up my system to the point of being unable to play any sort of game at all. I have to manually close it in task manager every time I boot. I'm on Windows 8.1 I've tried using super anti-spyware and Windows defender and nothing detected. Ran sfc /scannow and said there's a problem they can't fix or something like that (can upload log if needed) what else can I do? Don't really want to reset the system.
