114,000 viruses? Not on a MacBook!
According to Apple:
'By the end of 2005, there were 114,000 known viruses for PCs. In March 2006 alone, there were 850 new threats detected against Windows. Zero for Mac. While no computer connected to the Internet will ever be 100% immune from attack, Mac OS X has helped the Mac keep its clean bill of health with a superior UNIX foundation and security features that go above and beyond the norm for PCs. When you get a Mac, only your enthusiasm is contagious.
'Connecting a PC to the Internet using factory settings is like leaving your front door wide open with your valuables out on the coffee table. A Mac, on the other hand, shuts and locks the door, hides the key, and stores your valuables in a safe with a combination known only to you. You have to buy, configure, and maintain such basic protection on a PC.'
