I think for simple outbound protection, Zone Alarm 4.5.594 is fine. It has excellent logging and alerts with plenty of information about what they are. It's also very low on memory usage compared to many of todays Firewalls, plus there are no System or Internet slowdowns. I realize Comodo Pro, which I like very much, passes all the leak tests, but for my needs ZA Free is a nice replacement for my AVG FW. This version was one of the most stable ones of all, and runs well with Spyware terminator and AVG Antivirus. So I'll ask again. What's wrong with using ZA Free 4.5.594?
