Which Anti-virus are you running?....
This particular trojan is a nasty little bugger. You will need to disable System Restore before you attempt to remove as it can regenerate itself from here.
Once this has been done, do a full system scan (assuming the Anti-V you are running has found it, & it should be removed. Restart before you reactivate System restore .
According to Spybot themselves, that particular program can detect & remove this spyware/trojan so do an update from them & re-run With the system restore OFF.
I know its a little vague but hope it helps.
