That doesn't entirely add up to me. I mean you've got 3 OSs, all very different under the hood. How is one flaw in one 3rd party app going to allow the total takeover of all 3 OSs in the same method?
I'm not saying it's impossible, make no mistake. I just don't understand how that works.
If it said somewhere already posted in this thread - forgive me. I got 2.5 hours of sleep last night, and I've been up and running ever since. Why I'm awake - I have no idea.
To backup it affects every OS.
