Bitdefender Antivirus for Mac- Anti-Ransom Wear "Allow v. Block"?


In Bitdefender AntiVirus for Mac, to set up Anti-Ransome Wear Application Protection, I am confused about the drop-downs "Allow" v "Block"

If I add an application to the list, should I be choosing allow or block to ensure that the application WILL be protected from Ransom wear?

I am not a techie, and appreciate if someone can clarify this for me.
