Green check marks and ">>" on photos
I recently noticed that when viewing photos or files in Windows Explorer, I am seeing Green Check Marks or white on blue ">>" in the lower left of each photo or on the small icon for file names. Shortly after getting this machine (only a couple months ago) I installed Norton 360 and, in the course of events, also did a routine back up. I'm wondering now if those check marks and >> are indications of items backed up and items needed to be backed up?
I do regular scans so I don't believe there's any bad actors playing inside this machine. It is kind of annoying but I can understand the purpose if, in fact, it is 360 doing this. If so, is there a way to turn these icons (I guess you would consider them icons) off?
