It looks like the usual random naming of their file (cmvpzb.exe) that some of these trojans do, vinnyo123. I have removed hundreds of them in the past few years (from other peoples computers) without any problems. If VoG™'s link doesn't help, try manually removing (back it up somewhere first though) the cmvpzb.exe file and empty the Prefetch folder. If all is well after removing the file and after doing a scan with your anti-virus software, then turn off System Restore in order to delete all [probably infected] Restore Points. Then, if another anti-virus scan is clean, re-activate System Restore to create a new, clean Restore Point.
