ComboFix Reboot Into SafeMode

My Vista 32 bit tower will ONLY boot into safe mode - normal mode shows my desktop icons for 70 seconds (I timed it) and then always brings up an IRQL Not Less Than.... BSOD (0x0a).

I used another PC to get ComboFix on the desktop of the Vista, right clicked to run as Administrator, and was (eventually - almost 5 minutes) told that root-kit activity had been detected. A few more msgs later it informed me that Rootkit Zero Access had inserted itself into the TCP/IP stack, etc...

After another minute or so a msg came up that said the PC would now reboot to continue this removal process. I let it reboot and it booted normally, but I saw no indication of ComboFix continuing, and 70 seconds later, the BSOD.

I rebooted into safe mode again, and since there were no CF processes running I reran it, went through the same msgs and this time when it rebooted I pressed F8 and booted into safe mode with networking. Nothing. No CF processes.

I then changed msconfig to always boot into safe mode with networking, and went through the process yet again. It does all the right stuff up until the reboot. Now, even though it is automatically into safe mode, nothing further happens with ComboFix. It's been sitting there for 45 minutes after ComboFix's reboot, and believe me, nothing is happening.

How do I get around this?

 

I've already run TDSSKiller on the PC. It found nothing. I've already run a full Malwarebytes scan, and found nothing. The only tool so far that has detected anything is ComboFix, a tool I've used successfully many, many times. I simply figured that someone had encountered the same ComboFix problem as me, and wanted to know what they did about it.
I, of course, have no vested interest in ComboFix, and don't care what tool I use. If I have to download RougeKiller and HitmanPro and MGTools I'll do so, then I'll follow your scanning instuctions and report back.

 

Never mind. turning off UAC was all that was necessary.
