I know this was 8 days ago, but i had a similar, but not similar virus a bit back now. At first it just sat on my computer, doing nothing, but then i just decided to run an anti-rootkit scan to see what it finds, and it found a rootkit (im using avg free 2011). i was running malwarebytes anti-malware at the same time and i needed to restart to get rid of it completely, and i didnt because malwarebytes was still running, which was a VERY dumb move. Instantly after that, my computer said i had no anti-virus, when i tried to run avg, it just came up with an error message, i was ****. Basically, my grandad worked in IT, so he had a look at it. It wouldnt even get past the windows xp loading screen without it bluesreening. He thought the only way to get rid of it was to format the hard-drive, and re-install windows xp. So he did, and when he tried to install, it kept coming up with random files that couldnt be written to the drive. COMPLETELY ****

. So we sent it back to the shop, and guess what? They found that it had a RAM problem aswell, so they replaced it and its working fine.
So, i know how you feel alex

and sorry for the long-ass reply and the patchy grammar :/
Just one thing, did you have a good firewall installed?
and what does qft mean?
