PUM.Optional.ChromeEXTPOL is Malwarebytes' detection name for potentially unwanted modifications to the policies related to silently installed Chrome/Chromium extensions.
Malwarebytes checks the registry value 1 under the key
to check for potentially unwanted entries.
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.ChromeEXTPOL 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.
