An article in the Wall Street Journal of May 5, 2014 summarized what I have been talking about these last few years. 25 years ago, Symantec was one of the first IT security companies to develop commercial antivirus software to protect computers from hackers. Now the company says that's no longer working. Antivirus "is dead," says Brian Dye, Symantec's senior vice president for information security. "We don't think of antivirus as a moneymaker in any way." Mr. Dye estimates antivirus now catches just 45% of cyberattacks.
