I'm honestly not a fan of ZoneAlarm. I was big on it when I was fresh into the IT world, during my college years, but nowadays if a computer isn't already behind a hardware firewall, I just run Windows Firewall. It seems to do surprisingly well for an M$ app. I suppose ZA does its job, I'm probably just burned out from the dozens of remote users I couldn't remote into because they installed it, didn't know jack about configuring it, and couldn't figure out for the life of them how to turn it off.
