I find KIS 2009 firewall very effective due to it's HIPS feature. I am not using it at the moment, however when I was using it I enjoyed it.
You might want to set it up for maximum protection though. Take a look here if you do;

This may give you a few more popups etc. But the extra protection is worth it.
I must say I swapped KIS firewall for Online Armor due to the support being much better, and the overall experience and protection of the firewall.
@Karbo: I agree that the majority of users will not be able to understand the popups, which is sad because it is so useful
