Summary: PUP. Potentially Unwanted Program. An application that does not display malicious behavior yet is installed without having first sought affirmative user consent for installation. Users may not realize, due to the nature of the installation procedure, that an application they have not explicitly agreed to has been installed. This category can also be used to classify other applications which in a certain context can be wanted e.g. remote administration tools or IRC clients.
