Kaspersky antivirus or internet security?

[masta blas]

kaspersky antivirus is up there with the best of them, basically you should use kis if you're online often.

Would highly recommend NOD32, as it is very light on system resources. Did use Kaspersky in the past but found it to be a bit of a resource hog but not as bad as F-secure Internet Security was. Mostly recommend AVG free to people as it seems to do a fine job.

Was recently asked by a friend about comodo firewall, not one I'd heard of before. Does anyone have any experience of it?

Did used to recommend zonealarm but think the recent mess with a windows update stopping internet access has put a few friends off and they were wondering about an alternative..
