Cupertino, Calif, July 21, 1999 - Symantec Corporation (Nasdaq: SYMC), the world leader in utility software for business and personal computing, today announced Norton AntiVirus for Macintosh v6.0, the latest version of the world¹s number one anti-virus solution for the Mac. Improved scanning capabilities and powerful updating technologies make Norton AntiVirus for Macintosh v6.0 the most up-to-date and refined way to safeguard today¹s Mac computing experience.

"Norton AntiVirus for Macintosh v6.0 is the tool of choice for millions of savvy Mac users who rely on its powerful detection and repair technologies to maintain virus-free systems."

Norton AntiVirus for Macintosh is the number one virus protection solution for Macintosh computers. Version 6.0 provides fast, effective, and automatic protection against viruses that can enter Macintosh systems via web browsers, online services, e-mail, networks, floppy diskettes, and CDs. In addition, Norton AntiVirus for Macintosh v6.0 uses Symantec¹s next-generation Bloodhound heuristic technology to automatically detect and remove known and unknown viruses. Version 6.0 is PowerPC native and HFS+ compatible.

Improved scanning capabilities in version 6.0 increase system performance while enhancing overall protection against viral threats. Speed of initial scans, and subsequent virus scans are better than 20% faster than before. Norton AntiVirus for Macintosh v6.0 features asynchronous open scanning, improved scanning for unknown viruses, and removable media bypass. In addition, with version 6.0, users can configure Norton AntiVirus to scan archived files last.

Users can schedule LiveUpdate to run at regular intervals or can trigger it manually by pressing the LiveUpdate button.
