IBM Rolls Out Norton AntiVirus to Worldwide Network

- Symantec Demonstrates Commitment to Delivering Anti-Virus Solution to Enterprise Customers -

Cupertino, Calif --August 26, 1998-- Symantec Corporation (Nasdaq: SYMC), the world leader in utility software for business and personal computing, today announced that IBM will roll out Symantec's Norton AntiVIrus software across its entire internal network worldwide.

IBM agreed to install the software as part of the broad technology partnership announced in May in which the two companies said they would work together to deliver a single family of anti-virus products that would be marketed under the Norton AntiVirus brand name. As part of that agreement, Symantec will use IBM's patented immune system technology to produce a range of products, including new solutions to support IBM platforms. In return, IBM has turned over its existing anti-virus customer and OEM contracts to Symantec and now recommends Norton AntiVirus to its customers worldwide as the anti-virus solution of choice.

"By installing Norton AntiVirus on one of the world's largest computer networks, Symantec is delivering on its commitment to providing strategic anti-virus solutions to large enterprise customers," said Enrique Salem, vice president of Symantec's Security and Assistance Business Unit. "With this massive deployment, we are demonstrating our commitment to offer corporate customers a wide breadth of products providing uniform protection across all of the mission-critical systems in the enterprise. This rollout also strengthens our relationship with IBM Global Services and will provide them with the tools necessary to deliver the Norton AntiVirus technology within IBM and to other enterprise customers worldwide."

Norton AntiVirus
The Norton AntiVirus product line includes a multi-tier strategy that integrates products at the desktop, server, GroupWare server, Internet gateway and firewall levels to provide users with the most comprehensive virus detection and repair. The products provide users the security of knowing they have the most complete protection available whether downloading files from the Internet, opening attached word documents or accessing floppy disks. Norton AntiVirus provides users with 100 percent detection and repair of in-the-wild viruses, according to recent tests by Virus Bulletin.
