Symantec Ranked As Number One Security Software Provider In June Quarter

Customers Declare Norton AntiVirus the Top Choice for Virus Elimination

CUPERTINO, Calif. --September 19 1997-- Symantec Corporation (Nasdaq:SYMC), the world's leading supplier of anti-virus software products, today announced that in the hotly contested anti-virus marketplace, customers continued to demonstrate their overwhelming preference for Norton AntiVirus in both units purchased and total dollars spent.

According to recently released information from PC Data, Symantec sold 195,306 units of the Norton AntiVirus product line during the most recent financial quarter, while the number two vendor followed with sales of 155,423 units of their comparable product line. In dollar volume the comparable results are $11.3 million and $7.7 million respectively. In 1996, PC Data reported that Symantec's Norton AntiVirus was the top selling business software title for the entire year, following only Microsoft's Windows 95.

"While other vendors manipulate market data information to suit their own needs, the truth is the total volume sold of product through indirect channels, rather than in specific market segments, represents the true customer acceptance of a product," said Dana Siebert, vice president of the Americas, Symantec Corp. "Symantec's continued success is especially noteworthy because the number two provider released a new version of their product earlier this year and has begun to deeply discount the price of their product to respond to the dominant position of Norton AntiVirus."

The latest numbers from PC Data's Retail Report, which represents 60-70 percent of the total retail market, support Symantec's continued strong growth in the anti-virus market. While the entire category has averaged 14.5 percent growth per quarter over the last year, Symantec has pushed 15.5 percent growth over the same time frame, consistently outdistancing and taking marketshare from other anti-virus vendors. PC Data reported that during the most recent financial quarter, Symantec claimed 47.3 percent of the market based on unit sales, nearly 10 percent more than the closest competitor. In dollar volume, Symantec commanded 51 percent of the market, 15 percent more than the number two vendor.

The Norton AntiVirus product line includes a multi-tier strategy that integrates products at the desktop, server, Internet gateway and firewall to provide users with the most comprehensive virus detection and repair. The products provide users the security of knowing thay have the most complete protection available whether downloading files from the Internet, opening attached word documents or accessing flopping disks.
