Norton Security pops up messages about running in the background, I can't disable it

I'm running windows 7 Pro, and have Norton security.  The task icon in the taskbar pops up notifications when the software is doing something in the background.  The problem with this popup notice, is if I'm running QuickBooks or Quicken this message pops up right over the DOWN arrow on the sheet I'm working in using full screen mode.  It is an annoying feature, and I would love to turn it off, but there doesn't appear to be method to do so.  It does offer an 'X' to close the window, but it doesn't shut the popup down immediately, it lingers some before going away, THEN when I do close it I get another one saying it's done (same problem).  I lose about 2 minutes of productivity waiting on these popups go to away, its annoying.
