Intego has announced a free upgrade for users of its VirusBarrier X5 security software to eradicate malware from the iPhone and iPod touch. The company has been at the center of news regarding the rise of “trojan horse” malware targeting OS X since at least 2004, the subject of ongoing debate among computer security experts about the risks of malicious software and computer viruses infecting Apple systems.
Earlier this month reports of Apple’s having neglected its mobile platform in releasing security patches to fix exploits discovered in the OS X desktop caused some to wonder whether the opening of the AppStore might also open the door to software that could harm an iPhone or iPod touch. Apple has promised to use its gatekeeping role to screen malware from the AppStore, though, as Intego’s press release mentions, users “jailbreaking” (unlocking) an iPhone or iPod touch can install applications not pre-certified by Apple, increasing the risk of stumbling into harm’s way.
Thus far, the only harmful scripts or programs identified targeting OS X have required the inordinately reckless cooperation of users to open their systems and invite an attack, so the real risks are yet minimal. But as Macs begin to surpass double digits in desktop market share and Apple’s mobile OS continues to advance among handheld users, the prize for black-hat software developers grows ever larger. Perhaps Intego, makers of what MacWorld calls the “gold standard” of Macintosh anti-virus software, will one day rival Norton.

The Apple nay-sayers love to pretend that Mac OS X and all of Apple’s other products are destined to be destroyed by hackers. Although Apple has marketed its products as being far less hackable than Windows, someday, the Mac will just be riddled with viruses. It’s inevitable! Except that it’s never happened, and what do you know, Mac OS X is far less troubled by malware than Windows is.
