Norton symbol in the sys tray changed to a diagonal white line

My new HP is less than 30 days old and came with a 60 day trial of NIS (Which I do NOT plan to purchase because I have Norton 360 with one subscription available and having an issue with that, but will post as a different subject.)

 

The symbol in the sys tray changed to a white diagonal line rather than the green check mark.  I read a previous post that explained that the system might be slow and Norton is still loading.  I do not buy that answer as this PC is brand new and nothing excessive has been installed.  I ran a full system scan and all is good.

 

What does the symbol mean?

 

Thank you for any help.
