Completely removing Norton 360 from my Mac

My Mac is running very slowly at times, I want to completely remove it from my Mac. I’ve tried searching how to do this on the web, but the instructions I’ve seen for removing the program seem long, tortuous and don’t actually work for me. I always fall at the first hurdle - that being - to move Norton to trash from the applications folder but I can never do this because a message informs me Norton is in use. But Norton is not present in the ‘Force Quit’ table so I am stymied. Help please! Norton seems to make it very difficult to remove their products.

So, doc here does not help?
Before you follow the below steps, ensure that you close your Norton application, if it is already opened.
