CUPERTINO, Calif. -October 31, 2000 - Symantec Corp. (Nasdaq: SYMC), the leader in Internet security, today announced Norton AntiVirus Corporate Edition 7.5, which provides customers with enterprise-class protection at the desktop and file/print server tiers of the corporate network. Symantec's Norton AntiVirus Corporate Edition 7.5 is a key component of Symantec Enterprise Security, a comprehensive and modular Internet security solution for enterprise computing environments.

Norton AntiVirus Corporate Edition 7.5 is the only product in the anti-virus market with closed-loop automation technology. This technology is a part of the Digital Immune System, a sophisticated back-end infrastructure designed to provide enterprise customers with the highest levels of protection available. The Digital Immune System greatly improves system uptime by providing automatic, reliable, and hands-free virus detection, analysis, and delivery of virus cures to an infected PC or entire corporation with or without administrator intervention depending on the needs of the administrator. New flood control capabilities also decrease bandwidth problems that occur when too many users attempt to submit infected files.

"The increased use of the Web and the growing adoption of more Internet technologies provide fertile ground for viruses to spread quickly and in epidemic proportions," said Gail Hamilton, senior vice president, Enterprise Security Division, Symantec. "As part of Symantec Enterprise Security, Norton AntiVirus 7.5 enables customers to build the best security solution for their organization."

Norton AntiVirus Corporate Edition 7.5 includes several new features to ease administration and manageability:

• As part of the Digital Immune System, Internet-based Scan and Deliver now offers the ability to submit infected files to Symantec via the Internet using HTTPS, removing the reliance of an email-based submission system. Internet Scan & Deliver provides faster submissions, faster virus response time and increased security.
• Web-based installation support allows customers to point their clients at an internal Web server and download the software, thereby eliminating the need to rely on login scripts or third-party distribution tools. Support for resumable downloads eliminates the need to restart a download from the beginning if the connection is lost while downloading from an Internet Web server.
• Alert forwarding for lightly managed clients allows administrators to configure and lock-down client settings on hard-to-reach remote/laptop computers and configure centralized virus alerting for clients not managed by the central management console.
• Virus definition rollback gives administrators the option of returning to a previous set of virus definitions from the convenience of one central location. Administrators can also reinitiate missed events such as a scheduled virus scan, thereby ensuring maximum virus protection.
• Support node, an HTML viewer with a live link to Symantec Support, enables administrators to access timely service and support information without leaving their consoles.
• Symantec System Center provides an intuitive centralized console for customers who need to protect, control, and monitor their customers' machines from a single console. Administrators are able to set and lock down policies to ensure users are fully protected at all times.
• NAVEX™ technology maximizes system uptime and minimizes total cost of ownership by creating a single common extensible scanning and repair engine across multiple tiers-including Windows 9x, Windows NT, and Windows 2000-removing the need to reboot or re-deploy software.
