Norton crashes each week, have to reinstall weekly

I am running windows 7 pro 32 bit, Norton Antivirus 19.8.0.14. Norton ran fine for over a year, then in march I started having issues and the tech people at Norton would log in to my machine and reinstall Norton. This started as a once a month issue and has progressed into a weekly issue. I am so tired of installing and reinstalling this software. I have two other machines running the same operating system and programs and they have no issues. Have ran Norton power eraser numerous times and it finds nothing. The tech people find nothing, someone must know what I need to do other than switching to a different vendor software.
