"Spybot - Search and Destroy" is a nice little Spyware & Malware hunter :)
I would recommend it over ad-aware to be honest, ad-awares scan took way longer than spybots scanner, and spybots version found something!,while ad-aware found nothing.
Actually, use both. They're both manual scanners and I've noticed that neither catches everything, but both together catch most. It must be the difference in how they scan.
Just a thought.
