PUM.(Optional) is a category of Malwarebytes’ detections that deal with potentially unwanted modifications (PUMs). To learn more about PUMs, you can read the related blog content section.
Typically, PUMs are registry settings or browser modifications that could have been changed by PUPs or malware. You can find which settings have been changed and where by looking up the PUM detection profile.
PUM.Optional is a detection category only, so there is no protection against PUMs. But we do offer protection against the PUPs and malware that are known to make these modifications.
Malwarebytes can detect and remove PUMs without further user interaction.
When a 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.
