Doing this, I was able to work on the computer with no freezes, Avast also didn't give me any alert about the malware.
Anyway I grabbed MalwareBytes and did/am doing what sel and my friends in IRC have suggested. I did a quick scan first which brought up two problems with microsoft security center and now I'm doing a full scan.
If it doesn't find anything in this full scan, then I will have to try again to do a full scan with avast (I tried that in safe mode once and after 7 hours it had only done 8% of the scan... dunno if that was because of being in safe mode but urgh annoying.) I really need to get rid of some of the crap on my computer.
Gonna try and stay up until this scan finishes, then maybe sleep for a bit... so tired.
My brother said that he may come around to take a look at this too...dunno when though, hahaha.
