Mac users note new computer virus

Computer hackers have breached the previously pristine territory of Macintosh computers, a U.S. technology security director said.

Kevin Haley, director of security response at Symantec, said the first computer virus known to strike Macintosh computers had been detected in a few thousand Apple computers, CNN reported Wednesday.

The primary defense Macintosh computers have against computer viruses is their "relative obscurity," making them less desirable targets for pernicious programs, Haley said. "The bad guys generally go toward the biggest target, what will get them the biggest bang for their buck," he said.
