Non-stop messages: "Unauthorized Access Blocked" and "Intrusion Prevention"

I am getting non-stop status updates in my security history (literally every minute my computer is on for the last 2 weeks) with the following "medium severity" issues:

 

"Unauthorized Access Blocked" and "Intrustion Prevention..."

 

The "Actor" listed for the unauthorized messages are always from System32 or Lavasoft. 

 

Also, my computer randomly turned off by itself 5 times yesterday.

 

Does anyone know what these messages mean and why I could be getting them at all times?
