Have you tried Housecall?

It'll detect and pretty much remove anything out there for free. The only time it'll have a problem with virus removal is if the virus/trojan is still operating, then you'll have to find it via Task Manager and shut it down then run the scan again.
Hope thats some help yo yah.
