PUM.Optional.UserWLoad is Malwarebytes’ detection name for a potentially unwanted modification (PUM) in the Windows registry where certain executable programs are run when a user logs on the affected system. These programs are either dropped or downloaded to the Users and Documents and Settings folders by malware or PUP.
The following registry value data is modified:
load=*\Documents and Settings\*
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.UserWLoad could have been added to the system by malware or 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.
