Thats no suprise at all. Microsoft didn't "roll up their sleeves" for years because of all the anti-virus companies were, and still are protecting the Windows platform for them.
Meanwhile Apple was thumbing their noses that they didnt have virus's, and that was because there were hardly Mac's out there of any value outside of high end production editing systems. The tides have now turned and its now Apple out there with their pants down. Even though there are several anti-virus companies out there dealing with Apple, there are 30 years of culture thinking they are invincible.
