Some malicious attacks target the moment when a computer first starts when many security defenses are not yet active. It is important to have protection during this vulnerable time.
The following tests confirmed the results of many independent tests in terms of ZoneAlarm's effectiveness in stopping viruses, spyware, firewall attacks and other threats. ZoneAlarm significantly outperformed all competitors in stopping attacks during the PC start-up or boot.
Check Point Software contracted with KoreLogic (PDF), an independent security consulting firm, to create a complete malware life cycle test environment. The environment was deployed to assess the effectiveness of ZoneAlarm Internet Security Suite versus key competitors in detecting, mitigating and blocking the effects of malware on XP. Competing products tested were Trend Micro Internet Security 2007, Norton Internet Security 2007, McAfee Total Protection 2007, and Microsoft Windows Live OneCare. The testing program ran from March through May, 2007.
