Is antivirus software a waste of money?

Wired:

When it comes to computer security, Jeremiah Grossman, Chief Technology Officer at security consultancy White Hat Security, is paranoid — and for good reason. He’s seen what the bad guys can do. But when he met with Wired at the RSA Conference in San Francisco this week, he said something surprising: He doesn’t use antivirus software.As it turns out, many of his security-minded peers don’t use it either. The reason: If someone is going to try and attack them, they’re likely to use a new technique, one that most antivirus products will miss. “If you asked the average security expert whether they use antivirus or not,” Grossman says “a significant proportion of them do not.”
