I used to have Norton 360 but no longer have it. When I had it, it apparently created a backup folder N360_Backup on an external hard drive. Since I no longer have the app, I want to delete the folder. I have tried changing permissions and changing it from read only but the folder properties will not change and there cannot delete the folder. When searching on web, all instructions start with "start Norton 360" which I can't do.
I would appreciate any suggestions
