Need help (getting unusually high number of alerts) in security history

As the title says today for some reason I am seeing lots of the orange (medium) security alerts. Will clear it out and within a few minutes I see a dozen + new ones? Seems to be blocking firefox, movie maker and all sorts of things that were blue in the past or didn't even show up at all. Anyone else seeing this and does anyone know if this is a possible glitch with norton?

 

I have run a number of antivirus scans including malewarebytes and they all come back clean, PC seems to be running perfectly as well. Get my norton via comcast.
