Present system categories such apps as malware apps, which may create problems in a system. The more accurate/proper system is required to classify malware apps. This NASAM system classifies android applications with the help of recent feature extraction algorithm. In this system android features are taken from feature set to detect malware on four phases package, user, application, and validation phase. The malware detection is based on behavioural and classified according to their risk (High, Medium, and Low). This is useful for the user to handle the system (Application) very smoothly & will provide more secure system.
