Can you say with a straight face that if you were designing a system that had extremely high requirements of reliability that you would choose Windows over Linux? Like, all other things being equal? I'm sorry, but that would be an insane choice.
For instance, if you had to make deploy a mission critical server, assuming cost and other software was the same, would you choose Linux or Windows for reliability? Of course you would choose Linux.
But Linux isn't immune from this exact sort of issue, though - these overgrown antivirus solutions run as kernel drivers in linux as well, and I have seen them cause kernel panics.
