CUPERTINO, Calif. – June 4, 2003- Symantec (Nasdaq: SYMC), the world leader
in Internet security, today announced Norton SystemWorks 3.0 for Macintosh,

Symantec’s market-leading utility and antivirus products — Norton
Utilities 8.0 for Macintosh and Norton AntiVirus 9.0 for Macintosh – with
select partner back-up and uninstall utilities to deliver a full continuum
of disk repair, recovery and optimization tools.

“As any user who has experienced the loss of important computer files or
personal data will testify, the most valuable component of a computer
system is frequently the information it contains,” said Steve Cullen,
senior vice president of Symantec Consumer and Client Product Delivery.
“One of the easiest ways Mac users can safeguard that information is by
using Symantec’s Norton SystemWorks 3.0 for Macintosh, which
comprehensively guards against potentially disastrous events such as disk
problems, performance issues, and virus attacks.”

Norton SystemWorks 3.0 for Macintosh will include:

– Norton Utilities 8.0 for Macintosh, the most complete set of disk repair,
data recovery and optimization tools for the Mac platform

– Norton AntiVirus 9.0 for Macintosh, which now scans and disinfects both
PC and Mac viruses for added protection

– Retrospect Express Backup by Dantz, which stores backup files on
removable cartridges, DVD-RAM, compatible, CD-R/RW, MO, an external hard
drive, or even on a secure site via the Internet

– Spring Cleaning by Aladdin Systems, which completely uninstalls
applications and their associated files to regain disk space and sweep away
hard-to-find Internet cookies, cache, and history files

Norton Utilities 8.0 for Macintosh
Symantec’s Norton SystemWorks 3.0 for Macintosh includes a full version of
Norton Utilities 8.0 for Macintosh, which offers users the most complete
set of disk repair, data recovery and optimization tools for the Macintosh
