Many applications, such as download managers, antivirus, backup utilities, and Web browsers, are distributed freely via popular download sites in an attempt to increase the application’s user base. When such applications also include functionalities which are added as a means of monetizing the applications and may cause inconvenience to the user or compromise the user’s privacy, they are referred to as potentially unwanted applications (PUAs). Commonly used methods for detecting malicious software cannot be applied to detect PUAs, since they have a high degree of similarity to benign applications and require user interaction for installation. Previous research aimed at detecting PUAs has relied mainly on the use of a sandbox to monitor the behavior of installed applications, however, the methods suggested had limited accuracy. In this study, we propose a machine learning-based method for …
