Norton 360 autofix

Hi.  I ran autofix on the lastest version of Norton 360, as a full scan got stuck before completion.  The autofix found and repaired and installation error.  When I re-ran autofix, it again found and repaired an installation error - the same error is found and fixed every time I run autofix.  Does anyone know if this is something to worry about? 

Is it worth reinstalling Norton?  I am wary about doing this, as I tried this a couple of years ago, and had a lit of trouble reinstalling it.

I'm grateful for any suggestions.

Thanks

Richard
