Morals are a personal set of values that vary from member to member of a society. Collectively they form an understanding as to how one should behave socially. Ethics are more a professional set of values.
For example, I would say it's a moral choice whether or not to play GTA for certain reasons. It is also a moral and an ethical choice on the part of the creators of the game as to whether or not it is a right/good thing to do. Moral, personally, as "is it right to glorify this sort of behavior?", and ethical in that "is it right to profit off it as well?"
