Crypt XPack.Gen removal help

I've been using my WinXp SP2 machine for a while, mostly for browsing and some minor document editing. Recently it got infected with the Zpack/XPack trojan (detected by Avira), but was unable to remove it trivially.

I have two separate drives on my disk, one only with the windows & programs. So I reinstalled windows (formatted the original) in the hope that the trojan would be gone. That, surprisingly!, did not work and it's still here.

So here's my attempts to follow your prescription so far:

1. Ran SAS and performed complete system scan and removal of detected items. Log attached.

2. Ran MalwareBytes and performed quick scan. Removal of 1 detected item, and then reboot. Log attached.

After this, windows would start up but not explorer.exe. Attempts to start it from task manager gave a msg that you might not have the previliges required to access this. So continued further in Safe Mode.

3. In safe mode, I had to download and run combofix.exe. However, on running the file I got a message that it's not safe to continue when the combofix package has been compromised. "You may be infected with a file patching virus 'Virut' "

4. Had run MGtools earlier, and produced the zip file. So not running it again now.

Please do help -- how do I get rid of this annoying virus!

 

Thank you Chaslang for the grim prognosis. I had actually come to the same conclusion after some tinkering about, and saw how diabolical the virut virus is -- it starts to lash out only when you start to fight it. And lashes out good.

I did pretty much what you suggested, except I realized that this incident was what I had been waiting for.

Toughen up :major Pick up the shovel :major Dig a big moat & trench :major Install Ubuntu and leave windoze on the far, far side.

Thanks again, and btw -- this is my first time in a malware support site, and wow! you guys are doing a phenomenal job on a (very uphill?) battle! Good to see such sites and site admins.
