Hardly a week goes by without security fixes for the operating system or accompanying software applications
I Moved to Linux and It’s Even Better Than I Expected
Dan Gillmor

While more security updates are definitely better,they don’t guarantee security. Of course Apple has poor security record. But Windows are quite secure as long as you are on post XP and have allowed updates. I guess Kaspersky(or Symnatec) said Windows are most secure systems.

PS :not trying to say which is more secure just telling fallacy in logic
