Today I suffered a rather severe malware attack in the form of xp antivirus 2008. My desktop was changed to a spyware detected message and i experienced slowdowns.

First I tried to go at it manually by deleting its registry folder and the file in program files. Upon restarting with a clean Avast Boot scan, my computer froze soon after logging in. After many restarts/freezes and safe mode boots, I noticed a few things. First of all, my User name column in task manager was blank. Secondly, the program was coming back.....

Eventually, xp antivirus 2008 completely revived and began to pester me with false alerts, but I was able to operate in normal mode. I downloaded MalwareBytes and ran its scan which seemed much more effective than Avast and found many/all of the files responsible for xp antivirus 2008. Upon another restart however, I was suffering from the same effects as before: Freeze soon after login, and an empty task manager user name column. I have checked the registry and program files and don't see any sign of a malware reanimation, but only time will tell. At the moment, I'm operating in safe mode, and 800x600 is beginning to piss me off. Please help!

somehow my keyboard got unrecognized, so i had to use UBCD to reset all passes to blank so i could log in... the freeze still happens...

If you have deleted folders from the registry I doubt there is much hope of a recovery here and I would bet that is the issue. You could try an XP Repair as it makes some registry repairs. It won't remove anything except Windows updates and any added SP's.
