Here's the deal. Yesterday, at around 2:30am (meaning it was basically today,haha)I was on a video-streaming website watching TV shows, and I foolishly allowed the outdated Java script to run. After this, MSE, Windows Firewall, and Windows Update became disabled and i got error 0x80070424 when I tried to enable it. Scans with various programs showed that I had a decent amount of trojans. Then I decided to perform a system restore, and restored my PC to a restore point 2 days ago (july 18th). at this point, everything was working correcty, so i performed a scan with MSE and found the dreaded sirefef trojan. I deleted it, and to my surprise MSE actually said that it worked...and further scans showed up clean. I then did a scan with MBAM, and found a few trojans and adware programs that I promptly deleted..again it worked. i ran more and more scans throughout the day...and nothing was showing up - HOWEVER, during a full scan of MSE, my computer randomly restarted for no apparent reason...this has not happened since.
I've run scans with MBAM, MSE, HitmanPro, TDSSKiller, Norton Power Eraser, ESET Online Scanner (which found and removed a trojan and an adware program), EZ_Sirefix, ESESirefefRemover, SuperAntiSpyware, and ComboFix (I know I shouldn't have, but I did anyways - stupid, I know)
... and all of them have come up negative, other than the ESET Online scanner which i mentioned.
My question is: is it safe to say that my computer is free of this Sirefef/ZeroAccess malware, or should I simply do a nuke and pave (as I am aware that once the system is compromised with something like this, it really can't be trusted)?
also, if i were to do a nuke and pave, would it be safe for me to back up my documents? because the only thing that is important on my "infected" computer is some school documents..everything else is unimportant. will simple word documents and powerpoint files be infected as well?
and just to add, i am running windows 7 x64
