Hi! Thanks in advance for the help.

My girlfriend's PC has been infected with something very unpleasant - all indications currently point toward it being the ZeroAccess trojan or a varient therof.

I've tried a bunch of things already - I'm usually reasonably proficient at removing malware - and whilst 90% of the problems are gone, the core redirection and other issues remain.

I've also gone through all the steps recommended in the Preparation Guide, and I'll be posting those below.

Observable signs of the Malware

1) Google searches are frequently redirected to other completely unrelated sites. The redirection method appears to be through a form with a Javascript autosubmit.
2) GMER won't run with all features accessible, and gives the error message "Cannot create a stable subkey under a volatile parent key" on launch.
3) TDSSKiller won't run at all - simply does nothing on double-click.

Things I've Tried

1) Scans with Avira and Malwarebytes, both in Safe Mode and regular mode. Avira removed a bunch of virii, which were preventing Malwarebytes running, and Malwarebytes then removed a bunch more.
2) GMER and TDSSKiller, as mentioned. The Stubware also refuses to run.
3) System scans with BitDefender and Avari's bootable CD images, both of which found yet more malware.
4) A run of ComboFix, which informed me the system was infected with ZeroAccess. I've subsequently run ComboFix again, and the message didn't appear the second time.
5) A run of Rootkit Unhooker, which informed me there was possible rootkit activity. However, I'm not expert enough to know what to do with this tool, and it's at that point I decided to post here.


As mentioned above, GMER won't run.

Here's my Rootkit Unhooker scan result (all but Files, let me know if you want me to rescan):

OK, unfortunately we're out of time on this one. I'm going to fire up Boot and Nuke and, well, nuke the s(h)ite from orbit.

It really does look like it's the only way to be sure.

Thanks anyway, and keep up the good work! Hopefully other people will be able to clear the infection on their PCs - I see it's a bit of a plague right now.
