Auto Fix does not repair application failures!

I am getting some serious application failures in Norton Error Reporting that Auto Fix doesn't repair or acknowledge.  Some of these are: NAVEX32A, Ntdll, D3D10WARP.  Some of the errors are: SYMNETI, NCW, SYMNETDRV, CCSCANW.  I know we are suppose to ignore these but all are marked as "High" severity.  I run Auto Fix each time & it only repaired one item but I don't know which one. I have scanned with Full Scan & Norton Power Eraser, plus Malwarebytes & no infections were found.  Also did disc check and ran the System File Checker Tool.  I have Windows 7, SP1, 64 bit w Norton 360 Premier, ver. 22.5.2.15.  Windows 10 said my computer was not compatible so I did not upgrade.  Finally stopped it from trying to update to 10 everyday.  Should I uninstall version for Windows 10  to see if that helps or just do what they say: IGNORE!
