I got this Virus and Problem

[IcyBurn]

I got a virus and did a scan with malwarebytes and Avast and came out with around 800, I Know that's alot. I got them cleaned out as far as malwarebytes and Avast can find. Now everytime I turn on pc i get a virus found by Avast in the location of C:\WINDOWS\system32\8.tmp. Everytime I remove it, it comes back as a different letter or number but its always has .tmp and its in the same location.

Avast warning log
File name        C:\WINDOWS\system32\8.tmp
malware name  Win32:MalOb-U [Cryp]
malwaretype    Virus/Worm

Since that file, now I can't update avast or malwarebytes and TMPGEnc DVD Author 3 wont start up and I tryed uninstalling and reinstalling but nothen.

Update.
I tried SUPERAntiSpyware Professional and it found some and removed them and still cant update virus database and I just found out all virus program sites are blocked.

Thanks for the help anyone.

OK i just reinstalled windows and it was working fine till i got a file name 8.tmp and now i cant update any virus program or visit there sites. Does this mean im being targeted, I just did a fresh copy of windows and got it back in under 20 minutes.
