It's true. Even if some people are correct in that Macs get far less malware purely because of the lower marketshare, it still remains a fact: Macs get less malware. So does Linux. Thus posting that a Mac or Linux switch will lessen your malware problems is helpful and absolutely true advice. Relatively within Windows, suggesting to upgrade from XP to Win7 to lessen malware is also helpful and true advice. That doesn't mean such posters are spreading FUD about XP. "FUD" does not mean "any post you don't like."
You know if it was truly secure this wouldn’t happen.
I can make any computer truly secure by unplugging it and filling it with concrete. Otherwise, all running computers are susceptible to being hacked. The question is the relative security, and Mac easily has Windows beat. It's not my fault the security people want a MacBook Pro more than they want a Sony Vaio running Windows. Windows would have been hacked first had the desire been reversed.
Funny you added linux to the mix...at least most linux people understand that it is susecptible to getting a virus and that it has as many if not more security issues as Windows over the years. only Macbots believe OSX is more secure than the current flavors of windows and Linux.
