By bit, I mean bitch. AVG keeps popping up about every 5 minutes saying that %system32%services.exe is infected (generic trojan dropper, detected on open). The only option that comes up is to ignore the threat, because it's a vital system file (AVG has a "whitelist" of files it just won't touch). I ran a full system scan, hoping that it would come up with something, but it didn't even report finding the infection that it's been popping up for. I tried ComboFix, but aside from installing it does nothing, won't even give me a log file, unless I'm looking in the wrong place for it.

Any ideas, aside from formatting? I REALLY don't want to go through that right now
