You need to go into Extra Settings (the cog) in the Dell Backup and Recovery app, then uncheck 'overlay icon status.' (in Miscellaneous) I think that's right, my DBAR is doing a backup now and I can't verify. When it's done I'll confirm.
A lot of my folders, photo etc have a blue clock face and a red exclamation mark on them. Would like to know why and how to get rid of them ! Also Dell Backup and recovery wants money for upgrade. This all happened after Dell update.
