Mail using significant energy

My mail app is using significant energy. As of last week, the fans on my macbook have been running louder and more often than before and I checked the battery settings, and it shows Mail as using significant energy, which it did not do before. It also has a very high CPU percentage, which is unusual as well. Any suggestions? I am on macOS Catalina version10.15.6

To add to what Luis mentioned you'll need to uninstall all norton/symantic software according to the developer's instructions. You can check to see if you've removed all of the supporting files by downloading and running Find Any File to search for any files with the application's name  and the developer's name in the file name.  For example for the Norton/symantec software you'd do the following searches: 


1 - Name contains norton

2 - Name contains symantec

3 - Name starts with symi

4 - Name starts with symx


Any files that are found can be dragged from the search results window to the Desktop or Trash bin in the Dock for deletion.


FAF can search areas that Spotlight can't like invisible folders, system folders and packages.
