Guys, just to clear things up 
Ransomware Shield doesn’t detect - or protect you from Ransomware.
That is what Web -, Mail -, File System - and Behaviour shields do, and is the same for Avast Free and Paid.
Ransomware Shield walls off ( protect ) selected folders from unwanted modification by Ransomware, or other apps.
You can select protected folders, block or allow apps, and change protected file types.
That is also why I think Ransomware Shield is not the right name for this feature.
