Unauthorized Access Blocked

Forgive me if I'm in the wrong place. I'm wanting to know why I see "Unauthorized Access Block" in the Norton History and it's one after another seconds apart. Here's an example;

Actor:C:\WINDOWS\SYSTEM32\SVCHOST.EXE

Actor PID 6528

Target: C:\ProgramData\Norton\ {0C55C096-0F1D-4F28-AAA2-85EF591126E7}

Action:Open File

Reaction: Unauthorized Access Blocked

Can someone explain what this is and why it's happening, please.
