Short bio

PUP.Optional.Outbyte is Malwarebytes’ detection name for a family of potentially unwanted programs aimed at Windows machines. These programs ask money for services that are of no value or already included in Windows, for example defragmentation, driver updates, and registry cleaners.

Type and source of infection

These potentially unwanted programs are often installed by users themselves, that are looking for a problem with their computer. An initial scan usually shows a host of problems, but you are told you will need the paid version to fix all those problems.


Malwarebytes protects users against PUP.Optional.Outbyte by using real-time protection. Which gives users a chance to decide whether they want to keep on using the software.
