The guys at work recommend Kaspersky also. You can get it in stores for about $80.00 for three computers, or get the same version at purplus.com as a download (no disk, but you get a password for the other computers) for about$30.00 with no shipping fee because it is a download. You just have to make sure you pick the 2010 version and the right number of users. I think the single user download is about $25.00. Make sure to get the Internet Security, not just the Anti-virus.
Hope that helps,
