Symantec Announces New Norton AntiVirus Dual Protection for Mac

Protects Mac Users Running Both Mac OS X Leopard and Windows With Layered
Vulnerability Protection and Antivirus

Symantec Corp. (NASDAQ: SYMC), makers of Norton security software, today
announced the new Norton AntiVirus Dual Protection for Mac, featuring
vulnerability protection technology and antivirus for Mac users running
Boot Camp or Windows virtualization software -- programs that allow users
to run both Mac OS X Leopard and Windows operating systems. This solution
provides comprehensive protection from both Mac and Windows-based
vulnerabilities and viruses. With this dual protection functionality, Mac
users benefit by receiving both the number one selling Mac antivirus
solution -- Norton AntiVirus 11 for Mac -- and the award-winning antivirus
and vulnerability protection of Norton AntiVirus 2008 for Windows.

Mac users who run dual operating systems can now have comprehensive
security protection with automatic updates from Symantec's leading global
security network. Norton AntiVirus Dual Protection for Mac automatically
detects and removes viruses, scans and cleans downloaded files and e-mail
attachments, and incorporates discrete yet effective security alerts. In
addition, Norton AntiVirus Dual Protection for Mac is designed to
automatically update itself in the background, allowing users to conduct
their online activities without interruption. With Norton AntiVirus Dual
Protection for Mac, users get comprehensive protection for two operating
systems in one convenient and cost-effective package.

"As the popularity of parallel operating systems increases, Mac users are
at increased risk of vulnerabilities and viruses from threats targeted at
both Macs and PCs. This is why an extra layer of security is needed -- to
ensure users are protected against both sets of threats," said Rowan
Trollope, senior vice president, Consumer Business Unit, Symantec Corp.
"Norton AntiVirus with dual protection gives Mac users peace-of-mind as it
silently protects them from both Leopard and Window's-based attacks."

Norton AntiVirus Dual Protection for Mac provides an extra layer of
protection against attacks that target software vulnerabilities on Leopard
and Windows operating systems. This product includes both vulnerability
protection -- which is new to Norton AntiVirus for Mac -- and intrusion
protection -- included in Norton AntiVirus 2008 for Windows. These layers
of protection prevent threats from infecting systems by blocking malware
and viruses from installing when downloading pictures, music and software,
and then deleting the threat.

Norton AntiVirus Dual Protection for Mac also includes performance and
engine improvements to ensure better compatibility and less impact on
system startup and resource usage, so users can safely continue their
online activities without impacting their productivity.
