Firstly i'd like to thank everyone who replies to this. I am constantly impressed (and amazed) by the online community's willingness to help absolute strangers out with trivial problems. My trivial problem entails a very busy cpu (often running at 100% for extended periods of time). I've got a 1.73ghz pentium with 1gb of ram basically running the internet and office programs, meaning that i believe there is nothing insufficient with the specs of the pc to do what i'm using it for. so, evidence suggests that it's something software/virus related (in my opinion) so here's the hjt .txt file for your persusal. thanks a lot for any help.
