Malwarebytes for Windows detected a Potentially Unwanted Modification
PUM.Optional.DisabledRightClick is Malwarebytes’ detection name for potentially unwanted modifications (PUMs) in the Windows registry where the context menu—also known as the right-click shortcut menu—is disabled. As such, users won’t be able to see options when they press the right-click button of their mouse or trackpad while in the browser, on their desktop, or at a file or folder. These changes could be made by malware to hinder users from identifying, verifying, and removing it.
The following registry value data are modified or added:
Under
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\
Internet Explorer\Restrictions
From:
NoBrowserContextMenu=0
To:
NoBrowserContextMenu=1
Under
HKEY_CURRENT_USER\Software\Policies\Microsoft\
Internet Explorer\Restrictions
From:
NoBrowserContextMenu=0
To:
NoBrowserContextMenu=1
Under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\
CurrentVersion\Policies\Explorer
From:
NoViewContextMenu=0
To:
NoViewContextMenu=1
Under
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\Explorer
From:
NoViewContextMenu=0
To:
NoViewContextMenu=1
Malwarebytes can modify these registry value data back to their Windows default settings without user interaction.
Also, we advise users to do a full system scan as PUM.Optional.DisabledRightClick 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.
