What is “Potentially Unwanted Program”?
A Potentially Unwanted Program (shortly PUP or PUA) is an application that can contain adware, toolbars, or has other unuseful functions.
The term “Potentially Unwanted Program” was offered by McAfee to avoid labeling downloadable programs as malware. What makes such PUPs different from threats or malware? When you get a program from the Internet and forget to read the EULA, you might fail to recognize what various unwanted programs are being downloaded. Mostly, these Potentially Unwanted Programs are adware or internet browser hijackers. These unwanted programs change your default homepage and default search engine or show you not relevant ads.
