1-backup failed 2- performance scan: issues found ? 3-N360_BACKUP folder ...why at root?

1-Norton 365 Premium a message always on the home page :“performance scan: issues found” Why does it keep appearing on the home page? Is there a way to hide this message-ad???

2- Every time I try to sync my backup files are on an external USB hard drive… I always get an error message.“backup sync failed” (an error occured)

3- Also, could you place the folder with the N360_BACKUP backup settings somewhere else, e.g. in program files… and not in a visible location in the root of the disk where the operating system is located… because we usually avoid creating folders in the root ???
