ZoneAlarm Extreme provides a high-end, all-in-one PC security and tune-up utility for users who are looking for a supermarket approach to their computer's ancillary functions. Under the Extreme roof, you'll get an antivirus, antispyware, firewall, and parental control utility. Additional browser, identity theft, and e-mail protection are also rolled in, while extras like the free 2GB of encrypted online backup and the tune-up utilities are accessible but have components that must be downloaded separately.
The interface is smooth and modern, with big labels to draw your eye to the biggest features in each pane. A left sidebar collects what looks to be all the major features in the suite. We found it frustrating that some of the promised goodies, such as the online backup and tune-up utilities, were only accessible from the right side of the Main Overview tab. Many of ZoneAlarm Extreme's best features learn your behavior, so it's worthwhile to not pass judgment immediately. The firewall adjusts as it "sees" your browsing behavior. Likewise, the initial antivirus scan takes a long time--over an hour for us--because it builds a baseline for your system after it clears out any potential threats.
If you like or trust other ZoneAlarm products, Extreme should appeal to you. It's built on the various engines and algorithms that run their other programs, including ZoneAlarm Internet Security Suite and ZoneAlarm ForceField. However, it's a big suite and some users may prefer more nimble, individual components.
