PUP.Optional.Webthreat is Malwarebytes' detection name for applications that try to contact IP addresses or domains that are associated with potentially unwanted programs (PUPs).
When an application is found to make contact to a site or domain that is listed as related to a PUP in the Malwarebytes Web-protection module, the application will be flagged as PUP.Optional.Webthreat.
PUP.Optional.Webthreat is detected to protect the user against applications that want to download additional PUPs or from PUPs contacting C&C servers.
Should users wish to visit a blocked Domain/IP address and exclude it from being blocked, they can add it to the exclusions list. Here’s how to do it.
