PUM.Optional.DisableRegistryTools is the detection for potentially unwanted modifications (PUMs) in the Windows registry where users are prevented from accessing the standard Windows registry tools. For example, when attempting to run regedit, they will get the error message, “Registry editing has been disabled by your administrator.”
The following registry value data are modified:
Malwarebytes can modify these registry value data back to their Windows default settings without user interaction.
When PUM is detected on your computer, Malwarebytes for Windows does not know if 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.
To have Malwarebytes for Windows ignore a PUM, you must add the PUM as an exclusion.
When a PUM is excluded, Malwarebytes for Windows does not detect the PUM during scans or real-time protection.
