Hello, I suspect (quite sure) that I have a trojan horse in my system. It is currently residing in my system restore folder... I can only find it (but not remove it) with SUPERAntiSpyware but avast! and Malwarebytes' Anti-Malware fail to find it, but I am quite sure it is not a false positive. It keeps returning... Because of this trojan I got a problem that my system randomly freezes, mostly while playing games/watching videos. I did the 8 steps listed in that forum thread, if you want, I'll post the logs. My malwarebytes log is probably useless though, because it doesn't find any anything harmless and it is written in dutch :s . If there is no way that it can be removed or it is too hard or anything like that, I'll do a complete back-up of my hard drive with a ghost, before there were any viruses on it. I'd prefer not to do that except if I really have to. Thanks in advance!
