ZoneAlarm Subscribers Automatically Protected From New Internet Worm Attacks

San Francisco, CA - August 16, 2005 - Zone Labs®, a Check Point® company (NASDAQ: CHKP), announced this evening that users of the award-winning ZoneAlarm 6.0 line of Internet security solutions are proactively protected from the new outbreak of the Win32.Peabot.A worm (also known as Zobot.E), as well as any other threats targeting the Microsoft Windows Plug and Play Buffer Overflow Vulnerability (as described in Microsoft Security Bulletin MS05-039).

Without requiring any user intervention, ZoneAlarm's firewall is configured to prevent this Windows vulnerability from being exploited. ZoneAlarm blocks TCP port 445 – a file and printer sharing port, from sending or receiving information from the Internet. That default feature, active in all but the lowest of ZoneAlarm's security settings, is critical to preventing these types of destructive worms from gaining access to a personal computer.

If a customer does choose to lower their security settings, they are still covered by the SmartDefense™ Advisor, a rapid response update system intended to quickly react to emerging threats. Check Point, and the Zone Labs division, utilizes SmartDefense services to offer both enterprise customers and consumers early detection and protection from new virus, worm and other malware outbreaks.

Even prior to the update in SmartDefense, ZoneAlarm Pro 6.0, ZoneAlarm Antivirus 6.0 and ZoneAlarm Internet Security Suite 6.0 users all had a new additional layer of fortification called the OSFirewall™. The OSFirewall's proprietary advanced behavior-based monitoring system recognized the suspicious actions of the worms and prevented infections before any damage could be wrought–and before any anti-virus updates were available.

"We are committed to advancing Internet security technologies to significantly reduce the potential impact of these types of worms, and this latest attack is proof-positive that our strategies are working," said Gregor Freund, chief technology officer of Check Point. "Customers with proper security no longer need to wait days for anti-virus signatures to be updated before receiving relief. A multi-layer, comprehensive and preventative security solution will provide consumers and businesses alike with the right tools to keep their computer and network resources safe before, during, and after an attack such as Peabot.A."
