Re-installation caused by Defender problem

I need to remove and re-install Norton due to a conflict with Windows Defender.  Defender download seems to be hung up and I can't close Defender.  Norton Fighter has given me useful directions to remove Norton, close Defender, and reinstall Norton.    

This thread is just to ask for any details that I might need on using NRT and the re-install process (from Norton Fighter or anyone else).  Maybe there's a Norton link that spells it out for an amateur.  Or, maybe if I'm lucky, it's all pretty straightforward and self-explanatory.  :-)

Thank you.
