Hi

I have been having trouble with my PC slowing down over the last few months at startup and at other random times. I've looked at processes that are running but nothing seems unusual. I was thinking that I may have a cunning malware infection. Could someone please walk me through the immunisation process please? My Hijackthis log is below.

Cheers
