Apple removed an old item from its support site late Tuesday that urged Mac customers to use multiple antivirus utilities and now says the Mac is safe "out of the box."
"We have removed the KnowledgeBase article because it was old and inaccurate," Apple spokesperson Bill Evans said.
"The Mac is designed with built-in technologies that provide protection against malicious software and security threats right out of the box," he said. "However, since no system can be 100 percent immune from every threat, running antivirus software may offer additional protection."
Apple's previous security message in its KnowledgeBase, which serves as a tutorial for Mac users, was: "Apple encourages the widespread use of multiple antivirus utilities so that virus programmers have more than one application to circumvent, thus making the whole virus writing process more difficult."
Security experts, while pleased that Apple would urge Mac users to install antivirus software, had warned that running multiple antivirus products could cause problems and recommended against it.
Apple's antivirus support note was initially published last year and was updated last month, despite reports that it was a new note.
One Apple expert speculated that Apple was merely removing a poorly worded support note and said it probably wasn't ever Apple's intention to tell Mac users they need antivirus.
"I bet you it was a low-level support note and it hadn't gone through the right approvals," said Rich Mogull, security editor of Apple news site TidBITS. "That's my guess."
To some, Apple's latest move will be seen as back-tracking given that it comes one day after those misleading reports circulated. The motive remains unclear, particularly because Apple didn't replace the previously published suggestion with an updated one.
The message that remains is that Mac users don't really need to take additional steps to protect against viruses and other malware. Telling customers they can run antivirus for "additional protection" could be interpreted as a way to protect against any liability.
There are no known viruses in the wild that exploit a vulnerability in the Mac OS, and Windows continues to be the overwhelming preference for malware writers to target their programs. But malware isn't just taking advantage of operating system weaknesses anymore. In fact, the majority of such threats now come from code that targets weaknesses in browsers and other applications that aren't platform specific.
Mogull said he doesn't recommend that the average Mac user install antivirus software because of the low-level of malicious software seen for Macs at this time.
To me, this new Apple statement poses more questions than it answers.
Regardless of the meaning of Apple's latest action, I'm pleased to now have open lines of communication with the company. Over the last few months, I have had an increasingly difficult time getting any response to my e-mails and phone calls. For instance, I got no response to my requests for comment on Monday's article about this topic. However, after talking to several Apple spokespeople on Tuesday about the matter I am confident that the situation has been cleared up.
I also was reminded of how much collective knowledge CNET readers have about Apple and would like to extend an invitation for people to feel free to contact me directly at email@example.com with any feedback and tips related to Apple security issues.
