KASPERSKY ANTI-VIRUS STRENGTHENS SYBARI'S ANTIGEN E-MAIL PROTECTION TECHNOLOGY Cambridge, United Kingdom (April 30, 2002) - Kaspersky Lab, an international data-security software development company, today announced the integration of its world-famous award-winning virus protection technology, Kaspersky^TM Anti-Virus, into Antigen, one of the most popular comprehensive e-mail security solutions developed by Sybari Software. As a result, Kaspersky Lab makes its technology available for thousands of corporate customers all around the world that rely on the superior Antigen defense. "Antigen has earned worldwide recognition for protecting the integrity of its user's messaging servers and mission-critical systems," commented Natalya Kaspersky, Kaspersky Lab CEO, "We are extremely pleased to partner with Sybari to deliver a comprehensive and cost-effective solution against e-mail attacks of malicious code of any type to users around the world." KasperskyT Anti-Virus covers all reliable methods of virus protection: anti-virus scanners, resident "on-the-fly" virus interceptors, integrity checkers, and behavior blockers. Kaspersky Anti-Virus supports all of the most popular operating systems and applications. It provides strong anti-virus defense for workstations, servers, e-mail gateways (MS Exchange Server, Lotus Notes/Domino, Sendmail, Qmail, Postfix, and Exim), firewalls, and WEB servers. Kaspersky Anti-Virus relies on Kaspersky's database of over 60,000 known viruses and malicious code. The product is also powered by unique technology combating even future threats: the built-in heuristic code analyzer that is able to detect up to 92% of unknown viruses, and the world's only behavior blocker for Microsoft Office 2000 that provides 100%-guaranteed protection against any macro-viruses. Kaspersky Lab has gained worldwide recognition and industry praise for the superiority of its technology, including PC Magazine Russia 2001 "Editor's Choice" and PCBuyer'sGuide.com's 2001 "Editor's Choice" awards. In addition, the International Computer Security Association (ICSA), a respected authority in the field of information security software testing and certification, recently concluded testing of the company's Windows 2000 anti-virus solutions. The results of these vigorous tests conducted by ICSA confirm Kaspersky Anti-Virus software's compliance with the very highest world-class standards and have earned Kaspersky Lab the renewal of its certification. Sybari's Antigen is the only virus protection solution for the Lotus Domino and Microsoft Exchange environment with a choice of up to six leading scan-engine technologies. Antigen affords its users the flexibility to choose from the aforementioned leading scan-engine technologies for virus scanning when waiting for signature file updates during outbreaks, rather than being dependent on one virus lab for a cure. Since new viruses may bypass one engine, Antigen institutes an extra protection measure by enabling users to run multiple-scan engines, virtually eliminating network infection. The scan engines employed by Antigen have all been rated superior by various virus-testing labs and all consistently score high marks for their effectiveness in virus scanning. "Kaspersky's unique technology and the advanced level of protection it provides adds yet another layer of detection and defense to Antigen in the fight against the overwhelming number of virus threats rapidly spreading throughout businesses today," stated Tom Buoniello, vice president of product management for Sybari Software, Inc. "Our partnership with Kaspersky clearly reflects our continuing commitment to providing customers with the most comprehensive server-level antivirus solution on the market today."
