How can I remove the blue Norton 360 backup icons after turning off backup

I've decided not to use the backup feature of Norton 360, but even though I've turned backup off certain documents still have the blue backup icon on top of them, and new ones are added to new documents (despite backup being off).  How do I remove these icons, and really turn off backup?

From the classic interface of your 360, click on Settings and then in the Quick Controls section on the right, uncheck the Backup Status Overlays.
