As I go to my account management, I saw 4 of 3 seats are being used under Product Details, 4 out of 3???!!! and I don't recognize the other 3 names at all. This is not the first time already, I have been removing them again and again, but they just keep coming back, and sometimes with different names. Is my product key being hacked and used by other people? But under My device I can only see my computer.
