Apparently, Norton360 checkmarks all folders, files, pictures during backup. It can be turned off at Settings->Quick Controls->Uncheck the box Backup Status Overlays.
XP Home Edition Version 2002 SP3 Automatic Updates active. Toshiba
Recently, when I open a subfolder in My Pictures, all pictures are being modified by placing a double arrow to the bottom left of all pics.
It takes up helf of the icon, hard to see the picture.
I had recently installed Real Player 11.1.1
Thanks for any help
