I apologize for any and all perceived slights which I did not intend to send your way. Sincerely. If someone reads a different tone, then they cannot but also read a different message. And as for those slights which I did intend, well you probably deserved those. Let's be honest. You're not exactly a picture of moderation.
I never had norton notify me of that before. There is no way to know if it is some marketing trick, but I don't think that would be ethical to pull that kind of stunt on customers, so I take their word for it that they did find something wrong. I've never had them pull dumb crap like that on me before. I'm sure there is programs out there that definitely scam their customers, but I don't think Norton security is one of them.
