Hey guys thanx for your help so far hope u can help me more

ive attached my Hijackthis, AVG and SaS (superantispyware) logs for your viewing pleasure :P
My problem seems to have stopped since i ran all of the programmes asked, but thought i should post my logs neway to see if something got passed the bombardment of weaponry i used.
Basically my old problem was a process that was running after about 30mins of my computer being turned on details are:
Image name: windows (no .exe its just windows on its own)
User name: SYSTEM
CPU: 99
Mem Usage: 780,000K
so it was using up all my comp just to run this stupid process, but as ive said its seemed to have stopped thanx to u guys

.
Thanks in advance. Dread!
