Zone Labs Adds Antivirus to Consumer and SOHO Product Line
World's Most Trusted Security Vendor Introduces New Line-up for Award-Winning ZoneAlarm Family of Products, Including Best of Breed Suite

San Francisco, CA - May 24, 2004—Zone Labs®, a Check Point company (Nasdaq: CHKP), today announced the immediate availability of one of the best and most complete integrated security solutions to guard consumer and small business users from the risks posed by hackers, viruses, worms and other online threats. The flagship product in the new line-up is the ZoneAlarm® Internet Security Suite, an easy-to-use, comprehensive solution that provides all-in-one PC protection, integrating Zone Labs' award-winning firewall with antivirus, Web site filtering, privacy protection and instant messaging security.

Zone Labs also announced immediate availability for three additional members of the ZoneAlarm product family: the new ZoneAlarm with Antivirus, ZoneAlarm Pro 5 and ZoneAlarm 5.

"Zone Labs has always encouraged users to safeguard their PCs with our best-in-class firewall technology, paired with up-to-date antivirus protection," said Frederick Felman, vice president of marketing, Zone Labs. "We're proud to continue our commitment to best-of-breed solutions with the introduction of the new ZoneAlarm Internet Security Suite, which combines our time-tested and proven firewall – the best proactive defense technology – with award-winning antivirus technology to put unequaled security within the grasp of all users."

Both the ZoneAlarm Internet Security Suite and ZoneAlarm with Antivirus integrate Zone Labs' best-of-breed firewall technology with award-winning antivirus technology from Computer Associates. Computer Associates' antivirus technology has received the VB100 award for the past four consecutive years from Virus Bulletin, one of the world’s foremost antivirus testing authorities.

Ease-of-use is one of the biggest barriers to effective security and Zone Labs delivers innovative new features to remove this potential stumbling block. The ZoneAlarm Internet Security Suite and ZoneAlarm Pro 5 include a new Automatic Program Control feature, which is backed by patent pending systems to take the guesswork out of security and make it truly easy to use. Supported by the 30 million members of the Zone Labs security community and the experts at Zone Labs, users will have up-to-the minute advice automatically delivered to their computer about which programs are safe and which are dangerous. Automatic Program Control delivers on the promise of "set and forget" security, making the very best security accessible to users of all skill levels.

In addition, security has been further hardened across the entire ZoneAlarm product line with the addition of "boot-time protection," which begins protecting the PC before network drivers are loaded. This extra layer protects the PC at the earliest possible opportunity, thus providing no window of opportunity for malicious programs to communicate.

Uniquely, ZoneAlarm Internet Security Suite incorporates instant messaging security to ensure that IM conversations are private and secure, regardless of service or client used. Instant Messaging Security protects AOL Instant Messenger, ICQ, MSN Messenger and Yahoo! Messenger so that home and office workers do not have to change their existing IM habits or software in order to feel safe using the fastest growing form of Internet communication. The Message Encryption protects IM from eavesdropping while other IM security features defend PCs against IM spam, risks posed by IM vulnerabilities including common attacks like buffer overflows, invalid messages, unsafe scripts, and executable URLs.

ZoneAlarm Internet Security Suite allows parents to rest assured that their children's Internet experience will be free from the threat of pornography, violence and other dubious content. ZoneAlarm Internet Security Suite blocks inappropriate Web content dynamically to keep current with the tens of thousands of new offensive sites that spring up weekly, without requiring users to download large files. In addition, users may choose to block ads, as well as scan and remove third-party tracking cookies that violate users' privacy while allowing cookies from trusted sites to remain on the PC.

ZoneAlarm Pro 5
ZoneAlarm Pro delivers strong security features such as a personal "stealth mode" firewall to shield the PC from unauthorized entry, Program Control to prevent Trojan horses and spyware from stealing users' information via unauthorized communications with the Internet, as well as simple set-up for networks, including wireless networks. New in ZoneAlarm Pro 5 are Automatic Program Configuration and Program AlertAdvisor as well as enhanced ease-of-use and further hardening of security.

ZoneAlarm with Antivirus
ZoneAlarm with Antivirus is a new Internet security solution that provides Zone Labs robust firewall protection and antivirus in an easy-to-use package for home and small business users. ZoneAlarm with Antivirus is ideal for users who want a powerful best-of-breed firewall and antivirus but who are not interested in the additional security features found in ZoneAlarm Pro or the ZoneAlarm Internet Security Suite.

ZoneAlarm 5
ZoneAlarm, downloaded by millions of users and the de facto standard in the category, provides basic Internet security for the home PC. ZoneAlarm 5 has further hardened security to keep users and their valuable personal information safe, even against targeted attacks.
