Ransomware Shield and Dropbox / OneDrive and a Sharepoint network location

Avast Premier comes with Ransomware Shield.
Within the options for this shield are numerous auto-generated folders that are automatically protected by the shield, including several out of Dropbox and OneDrive.

However. Can I use Ransomware Shield to protect the root Dropbox and OneDrive folders? If so, would this protection filter down to all current and any new folders/sub-directories?

Same question for SharePoint.
Can I add my SharePoint directory to Ransomware Shield and have it protect it along with any current and any new folders/sub-directories?

Regards.
