In a recent interview with Computer Business Review's Steve Evans, Kaspersky Lab founder and CEO Eugene Kaspersky said Apple is "10 years behind Microsoft in terms of security."

"Apple is now entering the same world as Microsoft has been in for more than 10 years: updates, security patches and so on," Kaspersky said. "We now expect to see more and more because cyber criminals learn from success and [Flashback] was the first successful one."

"Kaspersky suggested that OS X's relatively low incidence of malware over the last decade has caused Apple to fall behind, while the abundance of viruses, worms, and trojans targeting Windows forced Microsoft to step up its game," writes Ars Technica's Chris Foresman.

"My guess is that Apple die-hards will discount his claims, and say that he has a vested interest in making people believe Macs are vulnerable, because that would increase sales of his software," writes Computerworld's Preston Gralla. "But they're wrong. He's not alone in saying that Macs are vulnerable; people have been saying that for years. Back in 2008 in the 'Pwn to Own' challenge, for example, it took only two minutes for someone to breach the Mac's security -- and the Mac's security was breached faster than was Windows Vista or Ubuntu."

"Apple appears to be heading in the right direction, though," notes The Verge's Tom Warren. "Mountain Lion, the company's upcoming OS X operating system due in summer, includes a new Gatekeeper feature that, by default, restricts applications from running unless they are from the Mac App Store or identified developers. There is an optional switch to enable all apps again, but it's clear this timely feature is designed to prevent malware from executing."
