New Protection Model Codenamed "Quorum" is Now Available in Norton 360 Version 4.0 Beta

After bringing to market a unique approach to the fight against cybercrime with
the award-winning Norton Internet Security 2010 and Norton AntiVirus 2010, Symantec Corp. unveiled data proving the effectiveness of the
powerful new protection model codenamed “Quorum,” now available as part of the
Norton 360 version 4.0 beta. The upcoming version of Symantec’s fast and light
all-in-one security suite features improvements to PC tuneup, backup and other
aspects of the product. Norton 360 beta is Microsoft Windows 7 compatible, as
are Norton Internet
Security 2010 and Norton
AntiVirus 2010.

“Basic security is not enough for today’s complex threat landscape,” said
Charles Kolodgy, research director of Security Products at IDC. “Consumers are
facing an environment of online threats that are fast increasing in number and
evolving in scope to put their identities and finances at risk. To maintain
their confidence regarding the Internet, consumers are turning to products, such
as Norton 360, that provide
multiple layers of security protection.”

Introduced last month with the Norton 2010 products, codename “Quorum” uses
the unique attributes of a file, such as age, download source, digital
signature, and prevalence, to assess its reputation. It also continuously
updates a file’s reputation as it changes over time. Since its release, the new
protection model is now tracking 70 million unique files, leveraging input from
more than 35 million anonymous Norton Community Watch members. In addition, the
technology currently identifies one million new files per week.

Leveraging this technology, Symantec has achieved unprecedented results in
third-party testing designed to compare the effectiveness of security products
against genuine threats consumers might encounter online. In tests conducted by
Dennis
Technology Labs, an independent UK-based lab that specializes in
“real-world” anti-malware testing, Norton Internet Security 2010 powered by the
new protection model was the only product out of 10 to achieve a perfect score
of 100 percent detection, compared to an average detection rate of 78 percent
across all products tested.

In addition to protection and performance, Norton 360 beta includes
improvements to the features valued most by consumers, such as PC tuneup and
backup. The latest version boasts enhancements designed to save computer users
time, improve PC performance and deliver “set and forget” convenience. Consumers
can save valuable boot-up time by using the Smart Start-up Manager feature to
reduce or stagger start-up applications. For backup users, Norton 360 beta
offers the ability to backup up files online, and to restore or access them from
anywhere via the Web.

“In the fight against cybercrime, we recognize that consumers need more than
just basic protection,” said Rowan Trollope, senior vice president, Consumer
Products and Marketing, Symantec. “Our technology’s effectiveness has been
battle-tested and proven in the field, and we’re including this new form of
security in the Norton 360 beta.”

Norton 360 beta includes additional key features such as the Norton Insight
family of technologies and enhanced versions of the recovery tool and Norton
Identity Safe. Also included in Norton 360 beta are SONAR 2, sophisticated
second-generation behavioral security technology that detects entirely new
threats based on their suspicious actions, without the need
