AMD announced today that AMD64 processors combined with the upcoming Windows
XP Service Pack 2 (SP2) will help computers to better withstand attacks from
certain classes of viruses and worms. The combination of the AMD64 processor and
Windows XP SP2 technologies will help provide customers enhanced security
allowing home and business users to experience safer e-mail and Internet
browsing, and increased network and memory protection.

AMD’s enhanced virus protection security technology in combination with
Microsoft’s Data Execution Prevention in the upcoming Windows XP SP2 is designed
to help render some viruses, specifically buffer overrun exploits, inoperable
and prevent them from replicating and spreading to other systems. All AMD64
processors, including AMD Opteron(TM) and AMD Athlon 64 processors shipped in
2003, are enabled with AMD’s Enhanced Virus Protection for the upcoming Windows
XP SP2. AMD64 processors are currently supported by more than 1000 global OEMS
and hardware and software companies. Windows XP SP2 is currently in beta and is
expected to ship in the second quarter of 2004.

"Computer security has become one of the most important issues in both the home
and enterprise, and AMD and Microsoft recognize that it will take a strong
combination of hardware and software to battle malicious code," said Marty Seyer,
vice president and general manager, AMD’s Microprocessor Business Unit. "AMD and
Microsoft are taking a leadership role with AMD64 processors and the upcoming
Windows XP SP2. We will deliver a solution that is both effective and easy for
customers to implement in either 32-bit or 64-bit systems."

"Data Execution Prevention is one of several security enhancements within
Windows XP SP2 that will provide our customers with protection against certain
buffer overrun virus attacks, thereby helping them become more secure," said
Rebecca Norlander, group manager in charge of the Windows XP SP2 release at
Microsoft Corp. "PC security is an issue that can only be addressed through the
combined efforts of our industry partners. The work that companies such as AMD
are doing provides an additional layer of protection for our customers when used
in concert with solid security practices at home and in the enterprise."

"By building threat resistance into next-generation systems at the platform
level, AMD’s enhanced virus protection will enhance one of the major pillars of
overall security management," said Lina Liberti, vice president of eTrust
product marketing at Computer Associates. "CA applauds this collaborative effort
and will continue working with both Microsoft and AMD to ensure that our mutual
customers can help reduce the effect of certain types of malicious code
polluting the Internet and reduce business risk."

"With multiple avenues for attackers to compromise a network through the
discovery and exploitation of vulnerable systems, a multi-layered defense has
become more essential than ever before," said Robin Matlock, vice president of
product marketing for Network Associates McAfee System Protection Solutions
Group. "As one of the first security companies to provide system protection for
the AMD Athlon(TM) 64 processors, Network Associates is pleased to support AMD
and Microsoft in their efforts to provide enhanced security technologies against
malicious threats. The enhanced technology will mean greater protection for our
mutual customers against both known and unknown attacks."
