Yeah, Spybot is slow.

Another thing to try: Somewhere on the Microsoft website is a program that checks for root kits. I don't remember the name, but I found it with a Google search for "root kit removal" or something similar. It's a Microsoft-written program and a free download from Microsoft. It's output is fairly technical, but by looking at the registry hooks that it reports and then running Google searches to identify the items listed, you can easily figure out which belong and which don't. Then you can go in and edit the registry to remove the malicious hooks. Warning: registry editing is not for the faint-of-heart. I did this successfully once when my XP-based desktop somehow picked up a root kit. However, it is an absolute last resort as manually cleaning the registry can easily render the OS completely inoperable.
