Black Hat Microsoft? (Score 0, Flamebait)

Perhaps this is a really dumb idea, but I can't get it out of my head. Please someone tell me I'm wrong and why. I can't stop myself from considering the possibility that there could be Microsoft lackeys that would purposely release malware for things like the Android so that people don't buy it. I feel like Microsoft has more than enough money to cover up their tracks too, so really - what's stopping them?
