Thanks for those links, malu - I wasn't aware that AVG had that second program.
The most annoying thing about ZoneAlarm for me is the hassle it takes to update whenever it sends you a reminder to do so. I seem to spend a ridiculous amount of time having to click through options that I don't want as they take the opportunity to try and sell me other products. Irritates the heck out of me. But apart from that, it's another hassle-free program for me. Does the job nicely, doesn't cost anything.
