Windows is DOS and was warmly welcomed into the personal computer age. Bad people was able to figure out ways to corrupt Windows because there were more of those program based computers compared to Apple Mac at 10% of the market. We didn't get picked on a heck of a lot - but Mac has become compatible and having to run DOS apps brings those possible nasties into our camp. OS X? I don't know if it's been a good thing. Things were way more better back in the OS 9 days. All Apple is doing is becoming more in tune with the electronic application of the way things are now and the bad guys are noticing. Especially now that Macs have gone Intel... These viral updates are actually needed for any help with this considered good and is better than none at all.
