Hi, borgencer. This is a known issue, and Symantec are working on a fix. No time frame as yet
It doesn't affect your protection and you can hide them, if they bother you in the meantime.
One thing that CAN work is to set your Boot Time Protection to Normal or Aggressive. The default is off.
Settings/Computer/Real Time Protection. I have mine set to Aggressive. That way Norton loads before other programs.
