Symantec AntiVirus Wins Record-Breaking 17th Consecutive Virus Bulletin 100% Award

Detects All Viruses in Virus Bulletin's In the Wild Tests, Generates No False Positives, and Scores 100% in Macro, Polymorphic, and Standard Virus Tests

CUPERTINO, Calif. - March 25, 2004 - Symantec Corp. (Nasdaq: SYMC), the global leader in information security, today announced that Symantec AntiVirus has won an unparalleled 17th consecutive VB 100% award from Virus Bulletin. To win the VB 100% award, Symantec AntiVirus detected all viruses in Virus Bulletin’s three In the Wild tests and generated no false positives. Symantec AntiVirus also received a score of 100% in Virus Bulletin’s three macro, standard, and polymorphic tests. Symantec AntiVirus earned perfect scores in all six Virus Bulletin tests last year as well, which makes Symantec AntiVirus the only antivirus product to receive 100% in all six tests two years in a row.

“Virus Bulletin is widely regarded as the premier international publication on computer virus prevention, recognition and removal, and its antivirus product testing is considered among the most thorough, fair and challenging,” said Arthur Wong, vice president of Symantec Security Response. “Consequently, it is an honor to see Symantec AntiVirus continue to perform consistently and flawlessly in Virus Bulletin’s demanding tests.”

Virus Bulletin reserves the VB 100% for antivirus products that detect all In the Wild viruses during both on-demand and on-access scanning in comparative tests and that generate no false positives when scanning a set of clean files. Symantec AntiVirus earned perfect scores in these tests to earn its 17th VB 100% award. It also scored 100% in Virus Bulletin’s macro, polymorphic, and standard virus tests.

“Symantec’s product detected all files in all test sets, leaving little room for discussion,” Virus Bulletin editors wrote in the February 2004 edition of the publication. “What’s more, the product managed exactly the same feat this time last year.”

According to Virus Bulletin, because the virus threat is continually changing, consumers and businesses should look for products that have achieved a succession of VB 100% awards rather than just one or two. Editors also emphasized that Virus Bulletin’s In the Wild detection tests are relevant because the viruses they test against are known to be causing real-world virus incidents and of doing so in more than just one or two isolated places. “Products that do not have full detection of these viruses are unlikely to be of widespread appeal,” according to Virus Bulletin editors.
