Walt Mossberg of The Wall Street Journal has written a column for Windows users today explaining how to protect themselves against the plethora of computer viruses going around these days. One of the solutions he provides is simply getting a Mac. “Opting out: The single most effective way to avoid viruses and spyware is to simply chuck Windows altogether and buy an Apple Macintosh. Apple’s operating system, Mac OS X, is harder for the criminals to infect, and the Mac’s market share is so small that hackers, virus writers and spies get little thrill, financial gain or publicity from attacking the platform.”
