Norton using CPU to max through Chrome?

Immediately after installing the Norton Internet Security Version 19.8.0.14, my computer has considerably slowed down. CPU usage according to the task manager is being affected the most by Google Chrome. However Google Chrome is the most used program, whenever I use pretty much any other program, the capacity is maxed out.

 

It hadn't happened before, but this has been immediately evident since installing NIS.

 

Any ideas if the problem could actually be NIS?

 

 

This is my current setup
