Is "Norton's urgent message" notification for real?

  I am using Windows 8.1 and every now and then I get a message, that flashes up on the upper right part of the desktop, that says something like: Click here for an urgent message from Norton.  I'm leary about clicking on links I don't know about.  Could this be a really urgent message from Nortons?  If it was a real message, would it not show up in the Report notice?  If this is a valid messge, is there a way to call the message back up?
