AV-Test also evaluates for false positives and potential performance impact. ZoneAlarm Extreme Security only flagged one false positive in a scan of 386,287 safe files. On a performance-impact scale of 5-25, with a lower score indicating less impact, ZoneAlarm Extreme Security scored a 7. This indicates you shouldn't see reduced speed in typical actions such as starting up, shutting down, and downloading and installing programs.
The bottom line
ZoneAlarm lacks some the fancy features that are becoming standard on similarly priced suites, such as support for mobile devices. But Check Point has focused its efforts on improving the protection factor of its product, and it delivers on its promise of "extreme security."
