G'day Marc,
try this root kit killer from Sophos. My staff have had good success with it and it's free:

Another thing we regularly do is mount the drive in a clean machine and scan from there. Finally, there are quite a number of linux Live CD's that have AV software specifically for cleaning up infected PC's.
