I've mentioned the antispyware/antivirus software from
www.malwarebytes.org
before. The basic version is free and one of the best programs I know of to get rid of spyware and viruses in computers running various flavors of Windows.

The paid version is the same as the free version but adds real-time protection, scheduled scanning, IP protection and scheduled updating. It's usually $24.99, but today only (February 14, 2010) it's available for $14.99 from this link:

I rarely plug specific offers here, but this is a good deal from a non-profit group. You get a license for ONE computer for this price, but you can buy additional licenses (again, today only) for the same price. It's a lifetime subscription--no annual renewal fees--and you can transfer the license to your next computer easily. So basically this simple $14.99 purchase will protect you for life on a single computer, assuming mailwarebytes.org stays in business.
