Earlier this week, an executive of the antivirus software giant Symantec told a reporter from the Wall Street Journal that his companys core business model \is dead.\ \We dont think of antivirus as a moneymaker in any way,\ Brian Dye, senior vice president for information security at Symantec, was quoted as saying. Because Symantec is a leader in the U.S. antivirus software market, both with its core enterprise business and with its Norton consumer division, Dyes comments that \antivirus is dead\ got a lot of attention.
