Zone Alarm isn't bad, I believe there's a freeware version on their site as well. Howerever, there is also Outpost, a freeware firewall that is a bit friendlier to use, and customizable for your own preferences, including content filtering for the "little ones" who may be using your PC.

InvaderSquoosh said:I recommend getting ZoneAlarm. It is a personal firewall that is independent of Microsoft's influences. Basically, it keeps an eye on what is using the internet on your computer. You'd be surprised what tries to get online. It can catch things that Adaware is not aware of, but the learning curve is a little steeper.
