ZoneAlarm is effective and easy to use firewall program that does a good job of keeping your computer safe from a variety of Internet threats. The program includes four interlocking security services: a firewall, an application control, an Internet lock, and Zones. The firewall controls and grants access to only the internet traffic that you agree to initiate. The Internet lock blocks traffic when you aren't using the Internet or when your computer remains idle. The Zone's module monitors all computer activity and alerts you when a new application is attempting to access the Internet.
