Norton not turned on message

A couple days ago, I got some error? messages after sending email from my Yahoo account.  I don't recall what they said.

 

Shortly after, I decided to do a scan and clicked on the Norton icon.  Northing happend, and I could not open Norton at all.  My action center showed a window saying Norton was turned off, and had a button where I could turn it on.  Not trusting anything I didn't do it.

 

I rebooted a couple times, and after the second (or third?) Norton was active again.  I did a scan and nothing was found.

 

Bottom line is I never disabled Norton, so why should I get an indication that it was off.   Anyone experienced anything like this??

 

Thanks.
