Symantec Brings New Version of Top-Selling Macintosh AntiVirus Software into Norton Family of Products

Norton AntiVirus for Macintosh 5.0 Provides Comprehensive, Automatic Protection in a Native PowerPC Environment

Cupertino, Calif. --May 18, 1998-- Symantec Corporation (Nasdaq: SYMC) today announced Norton AntiVirus (NAV) for Macintosh 5.0, incorporating the top-selling Macintosh anti-virus software into the Norton family of products. Previously known as Symantec AntiVirus for Macintosh (SAM), Norton AntiVirus for Macintosh is the most comprehensive virus protection available for Macintosh users.

New features available with this new version of Norton AntiVirus for Macintosh include automatic virus definition updates through LiveUpdate and seamless file repair through Auto Repair. Norton AntiVirus for Macintosh also incorporates Symantec's exclusive Bloodhound-Macro heuristic technology for detection and repair of new and unknown macro viruses, and expands the SafeZone beyond the desktop to the entire drive. In addition, like Norton Utilities for the Macintosh, Norton AntiVirus for the Macintosh now also features a bootable CD in case of an emergency.

"Symantec AntiVirus for Macintosh has been a top-selling product for the company since it was introduced in 1989," said Enrique Salem, vice president of Symantec's Security and Assistance Business Unit. "With the addition of LiveUpdate, Auto Repair and Symantec's Bloodhound heuristic technology, we will continue to provide our Macintosh customers the best protection on the market with Norton AntiVirus for Macintosh."

Automatic Virus Definition Updates Over the Internet
It is crucial for users to keep virus definitions up-to-date or risk rendering their computers vulnerable to the hundreds of new macro viruses that surface every month. Norton AntiVirus for Macintosh's new LiveUpdate feature updates users with the latest virus definitions via the Internet or via modem and can be scheduled in advance to run automatically. LiveUpdate will then continue to unobtrusively update virus definitions in order to ensure that the user's workstation remains completely protected against the latest threats. These updates, which are free for the first year, are automatically delivered and fully tested by the Symantec AntiVirus Research Center (SARC) at all times.

Unparalleled Protection Against Macro Viruses
Norton AntiVirus for Macintosh 5.0 provides users with complete detection and repair of in-the-wild viruses, viruses which pose the most significant threat to users. In addition, Norton AntiVirus 5.0 users receive cutting-edge protection against the rapidly growing number of unknown macro viruses through Symantec's revolutionary Bloodhound-Macro technology. While most anti-virus scanners are only able to identify viruses that have been pre-analyzed by virus researchers, the Bloodhound system uses heuristic technology to analyze programs, detect unknown or new macro viruses and enable the user to repair the infected file immediately.

Automatic File Repair
Norton AntiVirus for Macintosh also features Auto Repair that allows users to repair a file containing a virus instantly, without opening the Norton AntiVirus application. Auto Repair notifies the user when a virus or suspicious virus-like activity is detected. With Auto Repair, Norton AntiVirus for Macintosh provides users the ability to dispose of viruses quickly and automatically.

Bootable Compact Disk for Emergencies
Like Symantec's Norton Utilities for Macintosh, Norton AntiVirus for Macintosh comes on a bootable CD that allows users to start their computer if the hard drive fails. In an emergency, users can insert the Norton AntiVirus CD and restart the computer while holding down the "C" key. This will return the computer to a stable environment from which users can run Norton AntiVirus for Macintosh to locate virus problems and repair damaged files. The bootable CD also allows users to install Norton AntiVirus for Macintosh quickly and safely.

Faster Scans in PowerPC Native Environment
Norton AntiVirus for Macintosh is now PowerPC native, which means that Norton AntiVirus Auto Protect (formerly SAM Intercept) scans files for viruses faster than ever. In addition, Norton AntiVirus for Macintosh is HFS+ compatible, so users can scan hard drives and disks that are using the standard HFS file system or the new HFS+ extended file system format.

Universal SafeZone for Expanded Flexibility
The Universal SafeZone in Norton AntiVirus for Macintosh gives instant, automatic protection from most viruses. It acts as a "virtual clean-room" so copied or downloaded files can be scanned in isolation and declared "clean" before being used. The Universal SafeZone allows users to designate the entire drive as the SafeZone, not just the desktop, or a single folder or folders at a time. With Universal SafeZone file scanning, users find out effortlessly, on download, whether the file contains a virus.

Symantec AntiVirus Research Center (SARC)
Symantec's Norton AntiVirus product line is backed by the worldwide support of the Symantec AntiVirus Research Center (SARC). SARC comprises a dedicated team of virus experts who provide swift responses to local and global computer threats, actively researching and developing technologies to eliminate such threats, and educating the public on safe computing practices.

As new computer viruses appear, SARC develops identification and detection of these viruses, and provides either a repair or delete operation, thus keeping users protected against the latest virus threats. These virus definition updates are available to users of Norton AntiVirus, and are easily obtained by using the LiveUpdate or Intelligent Updater. LiveUpdate provides one-button, automatic access to the latest virus definition updates for registered users.

Pricing and Availability
Norton AntiVirus for Macintosh 5.0 will be available May 18. Norton AntiVirus for Macintosh has an estimated retail price of $69. Current SAM users can upgrade for $29. Current users of Norton Utilities for the Macintosh can receive Norton AntiVirus for Macintosh for $29.95. For a free 30-day trial version, visit the Symantec web site at http://www.symantecstore.com/trialware/index.html. Virus definition updates are free for the first year. After the first year, customers who purchase the product before Dec. 31, 1998 can buy a subscription to the virus definitions for only US$3.95 per year.

Minimum System Requirements
