I hate to say it, but I have used all three of those services without any sort of problem, is it possible that your computer has had a security breach?
I had no problem either, until I did.
isn't this like saying "hey, I also drive a car and I have never had an accident"?
To follow your analogy, you've had 3 car accidents driving 3 separate cars, and I've driven those 3 cars just fine without an issue. Not saying that I will never have an issue....just saying that I haven't yet.
