I used the Norton removal & reinstall tool recently to completely remove Norton.

However if you are uninstalling permanently please be aware that it still leave remnants behind & after restart has a very annoying pop-up asking if you’d like to reinstall again.
I had to check under startup for any Norton entries & run Revo Uninstaller Pro to search for Norton & I was shocked at how much the official uninstaller had left behind.
