Firefox wont close


In Runtime
Alright I think I may have a virus but im not sure... My firefox will never close out, it is always in my processes no matter how many time i click end process it always comes back. also when i restart sometimes my windows explore will come up with an error, or i just get a white screen with just my windows taskbar at the bottom... i have NOD32, Spybot S&D and i run trendmicro's and ewido's online scanners and havent found anything besides the normal coockies... ive ran them in safe mode as well

this is my HiJackThis Log but I also dont really see anything bad:

Ive also reinstalled firefox with no luck


In Runtime
alright so i fixed the firefox prob by doing a system restore. but in the process my sound driversdissappeared and so did one of my network connections, also ive noticed one of my svchost.exe's taking up 50% of my cpu and 62MB of ram... ive done scans with EVERYTHING i can think of; NOD32, Spybot S&D, Trend Micro Online scanner, ewido online scanner, CWShredder, Hijickthis log came back clean, i tried AVG Free version... i cant think of anything else, they are all coming back clean, im starting to think that it my be a corrupt file somewhere i tried sfc /scannow but that didnt help
