Need help removing Malware/Trojan

Well, i downloaded avast and restarted my computer. Now about every 5 minutes i’m getting a popup from avast saying malware blocked/trojan horse blocker.
The following reads:
Object: C:\Windows\Installer.…\80000000.@
Infection: Win32:Malware-gen
Action: Moved to chest
Process: C:\Windows\System32\services.exe

I tried doing a full system scan to delete it, but every time I do so, it always finds a way back.

follow the guide and attach (not copy and paste) the requested logs
http://forum.avast.com/index.php?topic=53253.0

I just did so and here is the aswMBR log.

Notes:

  1. Do not mouse-click Combofix’s window while it is running. That may cause it to stall.
  2. Do not “re-run” Combofix. If you have a problem, reply back for further instructions.
  3. If after the reboot you get errors about programmes being marked for deletion then reboot, that will cure it.

Please make sure you include the combo fix log in your next reply as well as describe how your computer is running now

It seems to be running better, i don’t seem to have those annoying avast infection things popping up. heres the log.
