I currently have Kasperkey Internet Security for 3 users. It is about to
expire. I'm wondering if I should purchase the 2010 version of it I
should buy the Kasperkey Anti-virus instead. What is the difference and
which one is better?

As others have alluded, if you have a separate firewall (hardware or
non-Kaspersky programme), get KAV 2010. If not, then get KIS 2010.
