The following registry value data is modified:
Malwarebytes can modify this registry value data back to its Windows default setting without user interaction.
Also, we advise users to do a full system scan as PUM.Optional.DisableShowSearch could have been added to the system by malware or PUP.
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.
