Funny look at virus protection for Mac users:
Without any in the wild viruses to infect your Mac, does your Mac need virus protection? My neighbor thinks so. I don’t think so. But I don’t have an answer for, “How do you know?”
Remember, a virus is merely one part of what is known as malware—malicious software, Mac or Windows. That could be viruses, trojan horses, scareware, crimeware, adware, spyware, worms, rootkits and other nasty pieces of software—prominent in the Windows world; for Mac users, not so much.
So far, no in-the-wild viruses for Mac OS X.
