Symantec Develops World's Largest Online Encyclopedia of Computer Viruses

SARC Offers Premier Anti-Virus Resource on the Internet

Cupertino, Calif. --December 5, 1997--Symantec Corporation (Nasdaq: SYMC), today introduced the world's largest online encyclopedia of computer viruses with more than 10,000 comprehensive descriptions, developed by the Symantec AntiVirus Research Center (SARC). The virus encyclopedia is a valuable resource for a company's MIS department, for small business owners or for anyone who uses the Internet and experiences frequent virus attacks. It is currently available online at www.symantec.com/avcenter/vinfodb.html. Norton AntiVirus 4.0 customers can click on the "Virus Encyclopedia Online" option in their Windows 95 start menu to connect directly to the site.

"Computer viruses are a big mystery to a large number of people today," said Alex Haddox, product manager for the Symantec AntiVirus Research Center. "The SARC encyclopedia, as well as the entire SARC site, provides a vast resource on computer viruses and ways to combat them. Educating the public on the real threat of computer viruses is a strong component of the SARC charter."

In addition to descriptions of individual computer viruses, the encyclopedia also gives a detailed overview of computer viruses in general, the different types of computer viruses, virus threats specific to the Macintosh platform and various virus hoaxes. The encyclopedia also provides a direct connection to SARC, where Norton AntiVirus users can download their free virus definitions. The encyclopedia will be updated every month as definitions and descriptions for new viruses are created.
