PC VIRUS - XP Security Centre

I discovered this last night, it had rebooted my computer and this was popping up from the very start of my desktop opening.

I was unable to run Vundo, CCleaner or Spybot and it's disabled my McAfee virus protection. I panicked so I have disabled my internet connection but left the computer running. I tried a scan with a Malware Remover but this programme just disappeared and didn't give me any results.

Does anyone know how I can get rid of this virus/malware/trojan?

Will it let me do a system restore, maybe to about 3 days ago when I know it worked well?



This virus came from an email titled "Statement of fees 2008/09".


I just run and done a scan with "Malwarebytes’ Anti-Malware" it found many bad things and deleted them but now says the following

" files that are required for windows to run properly have been replaced by unrecognised verisons. To maintain system stability windows must restore the original versions of these files. Insert your home XP edition CD rom now"

I cant find my CD rom, will my PC restart if I reboot this now without the CD rom? Is it too late for a system restore?
