Brian X. Chen:
Should Mac customers install anti-virus software by default like
most Windows customers do? Charlie Miller, a security researcher
who has repeatedly won the annual Pwn2Own hacking contest by
hacking Macs and iPhones, told Wired.com he doesn’t think so.
Miller noted that Microsoft recently pointed out that 1 in 14
downloads on Windows are malicious. And the fact that there is
just one piece of Mac malware being widely discussed illustrates
how rare malware still is on the Mac platform, he said.
