Malwarebytes for Windows detected a Potentially Unwanted Modification
PUM.Optional.ConnectionControlRestriction is Malwarebytes’ detection name for a potentially unwanted modification (PUM) in the Windows registry where users are prevented from accessing the Connections tab in Internet Explorer. Typically, browser hijackers alter this setting to hide the changes they made to the users’ connection.
The following registry value data are modified:
Under:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\
Internet Explorer\Control Panel
From:
ConnectionsTab=0
To:
ConnectionsTab=1
Under:
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft\
Internet Explorer\Control Panel
From:
ConnectionsTab=0
To:
ConnectionsTab=1
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.
When a Potentially Unwanted Modification (PUM) is detected on your computer, Malwarebytes for Windows does not know whether it was authorized. Optimization software, malware, and Potentially Unwanted Programs (PUPs) are known to make these types of changes, hence they are regarded as potentially unwanted by design.
To have Malwarebytes for Windows ignore a PUM, you must add the PUM to the Allow list. Here’s how to do it.
