Quieter yet more effective, the latest ZoneAlarm Firewall Free should be considered an excellent tool for replacing the otherwise adequate default Windows firewall.

It's a stronger option that includes quieter outbound protection, behavioral detection from the ZoneAlarm Internet security suite, automatic Wi-Fi security setting activation, antiphishing protection, an overhauled ZoneAlarm toolbar that will protect you even when hidden, six months free identity theft protection, and 2GB of free online storage.
