Third-Party Test Finds Norton Internet Security 2009 Protects More Effectively Than Other Security Suites

CUPERTINO, Calif. – Dec. 8, 2008 – Symantec Corp. (Nasdaq: SYMC) announced today that Norton Internet Security 2009 received a perfect score and was named the top-rated product in a comprehensive analysis of protection in security suites conducted by third-party testing organization Cascadia Labs. Recently engineered with performance as a key focus, Norton Internet Security 2009 and Norton AntiVirus 2009 also received top marks in overall performance in a comprehensive test conducted by PassMark Software, beating out competitors like Avira, ESET, Kaspersky, McAfee and Trend Micro.

"Today's malware authors are moving much more quickly, developing new threats and deploying new techniques to infect computers. According to Symantec's most recent Internet Security Threat Report [1], more than 700,000 new threats were detected in 2007, an increase of 468 percent," said Rowan Trollope, senior vice president, Symantec. "Now, more than ever, it's critical for computer users to protect themselves with a strong security solution, like Norton Internet Security, that doesn't compromise performance and also protects against today's threats more effectively than freeware and less advanced solutions."

Cascadia Labs analyzed the effectiveness of popular consumer security products in protecting computers against web-based attacks. These threats, also known as drive-by downloads, often take advantage of vulnerabilities in a website to infect unsuspecting visitors' computers simply by viewing the site. Norton Internet Security 2009 was evaluated against AVG Internet Security 8.0, Kaspersky Internet Security 2009, McAfee Internet Security 2009 and Trend Micro Internet Security 2009. In every measure of the test, Norton Internet Security 2009 performed flawlessly, blocking 100 percent of the exploits tested against it.

Norton Internet Security 2009 was the only product to receive a perfect score of 50 out of 50 in overall effectiveness of fake application blocking and drive-by download protection. Norton's effectiveness in blocking exploits was nearly twice that of the nearest competitor. According to Cascadia Labs, "Norton's approach of focusing on the vulnerability that an exploit targets, rather than relying on specific signatures that can quickly get out of date, proved highly effective in our testing." In contrast to competing approaches that require users to scan for web browser vulnerabilities and apply patches, Symantec's Browser Protection feature works seamlessly with no additional user action required.

In addition, Norton Internet Security 2009 blocked every fake AV scanner and fake video codec site tested, with the nearest competitor blocking only 60 percent of the fake scanners and codecs and the remaining competitors blocking fewer than half.

Specifically, PassMark found that both Norton AntiVirus 2009 and Norton Internet Security 2009 installed faster, scanned faster, used less memory and required less disk space then every major competitor.
