(Nasdaq: SYMC) today announced that PC Data sales statistics clearly show Norton Internet Security 2000 as the leading Internet security solution in the fast-growing Internet security software category.

PC Data is the computer industry's primary source for software, hardware, and video game sales information.

In addition to demonstrating the unparalleled popularity of Norton Internet Security, the PC Data figures also indicate the product's role in defining and driving the Internet Security software category. Weekly sell through for Internet Security products for the month prior to the introduction of Norton Internet Security (November 1999) averaged just over 1,500 units. Since Norton Internet Security hit the market in December of 1999, average weekly sell through for the category has grown to over 4,800 units representing a 220 percent increase in the weekly volume for Internet Security software. Additionally, Norton Internet Security has captured over 60 percent of the market volume and over 80 percent of the category revenue since its introduction.
