"Historically, we have always seen a jump in security sales that correlate to highly publicized security issues," said Baker in an email reply to questions. "[But] the spike seems to be declining over the years as more consumers use and recognize the importance of security software."
Some Mac owners have been skeptical of the claims that Flashback has infected hundreds of thousands of machines, and have accused antivirus vendors like Dr. Web and Kaspersky -- the two Russian companies that have calculated the extent of the malware infection -- of hyping the threat to sell software.
One Sophos executive addressed those critics in a blog post today.
"For those of you inclined to let rip in the comments that I'm only discussing Mac malware, and talking up the risks, because we happen to have a free product to 'sell' you, please consider an alternative explanation," argued Paul Ducklin, who heads Sophos Asia-Pacific technology team. "Perhaps the reason we have a free product to 'sell' is because we think there is a genuine risk?"
Flashback had infected nearly 2% of the Macs that used Dr. Web's free checking tool, and the malware's makers currently control more than 650,000 systems.
Apple, which updated Java for Mac OS X on April 3 to quash the bug Flashback has been exploiting, promised yesterday to release a free detect-and-delete tool, probably within the next week.
