I am running Win XP Pro. Two days ago it just started running incredibly slow. I checked Task Manager and an svchost.exe was running at over 400, 000 Kbs. I have run everything I know, Combofix, Malwarebytes, TSSkiller, Rkill, Superantispyware all multiple times. It took out malware and cookies, but not the culprit. Any ideas on what to do? When I boot up i watch taskmanager and watch this slowly rise until it takes all my resources and I can't do anything (even in Safe Mode).
