Hey guys. I just ended up formatting the drive and reinstalling XP. I'm using Norton Ghost to create a backup image of the C drive once I've installed all my updates, drivers, and basic software, so if anything like this ever happens again all I have to do is revert to the backup.
Cheers for all your help. And as for AV, I'm using Spyware Doctor and McAffee. I didn't have Spyware Doctor installed before the virus got me so I reckon that made it a lot easier for it.
Also,
another thing to watch out for with this virus:
I managed to beat the virus down quite a bit, so much so that the listed dangerous files (related to AntiMalware Doctor) were gone off my computer, the dangerous registry values were gone, and the "program" didn't start up automatically upon login. However, I was getting a constant message from Microsoft Security Essentials saying it detected a Win32/Trojan of Severe Threat.
I've used MSE before so this didn't seem out of the ordinary. I clicked "Clean Computer", and then it just left me with an option for "Scan online".
Ok? Click that. It gives me a list of known AV programs such as Kaspersky, McAffee, Norton, AVG etc. and tells me which programs are capable of removing it, and offering "free download". This is where it looked a little suspicious. I didn't want to install any more software to the computer, so I just got fed up with MSE and went to remove it from my computer. It didn't exist
I remembered then that I'd never installed it since my last OS install.
Long story short: The virus can pose as Microsoft Security Essentials, and it looks IDENTICAL to the real thing, so be careful.
Also, another way to catch and activate the virus is to click on the "Windows Update" splash it throws up, which, once again, looks identical to the real thing. So be careful.
