PC crawling. HJT log. Need help!!!

My PC is grinding to a halt and I can't find the reason why. Evertime I try to open My Documents or Windows Explorer etc the little torch scans for ages as if the files aren't there. It can take minutes to close Windows Explorer. AdAware and AVG scans show nothing. I don't know how to read the Hijackthis log files. Can anyone help with this?

Logfile of HijackThis v1.98.1
