I read many posts on MT forum and some other forums about using Behavior Blockers. It seems that there is no general agreement on what are the capabilities of Behavior Blocker (BB) and which AVs use Behavior Blockers (BBs). So, I made a little research to clarify this.
I did not find any widely accepted definition of BB, because AV vendors used very different definitions for their BBs. But, there are some sources which can tell what BB is not.
