Under:
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\
Internet Explorer\Control Panel

From:
ConnectionsTab=0

Remediation

Malwarebytes can modify these registry values data back to their Windows default settings without user interaction.

Also, we advise users to do a full system scan as PUM.Optional.ConnectionControlRestriction could have been added to the system by malware or a PUP.
