Preamble: I'm usually VERY careful about not installing unwanted things. This is the first time I've dealt with an infection so severe that I needed to consult the forums. Please note that I've done my research and I'm prepared to reformat, but I have a lot of important files to backup, so if there's any way to save the PC, I'd appreciate the help.


The Story: This afternoon, I left for work and kept my computer on (I also left a p2p filesharing program running); I came back a few hours later to find that it had shut down, and when I booted it back up, Microsoft Security Essentials told me that it had detected (and "cleaned") a virus when I opened Chrome. 


However, every time I opened a new page in Chrome, that message would pop up again. It told me that I needed to restart my computer to fully eliminate the virus. Like an idiot, I followed the instructions and restarted. While Chrome is now clean, the virus (ramnit) jumped to two other applications. I checked my firewall and system restore and both were disabled (can't re-enable due to registry error; that's probably compromised too).


Right now, I've been going through my Event Viewer logs, looking at all the file locations with reported malware and manually deleting them. I've also been using Hijackthis to try to clean my registry. I'm also researching registry trackers/cleaners to try to fix that. Is there anything else I can do?


Quick summary:


Antivirus: Microsoft Security Essentials

Infections: worms, trojans, possibly botnet?

Detected & "Cleaned" Viruses: Ramnit, Evotob-A/B/C, Rustock

State of PC: Severely infected but I can still use it to make this post; I wouldn't dare do any personal banking on it, though.

Firewall: disabled, can't enable due to Error 0x80070422


Any suggestions?


edit: According to the Event Viewer, right before my PC shut down, MSE attempted to update definitions (which I keep up to date anyhow) but failed.
