In order to improve the effectiveness of mobile malware detection, the optimized euzzy C-means(FCM) clustering algorithm is used to classify and detect massive amounts of malware automatically. Firstly, this paper presents a new algorithm named of intelligent bat algorithm(IBA) by introducing a gravitation operator to enhance the linkage of the Bat algorithm, and uses it to optimize the FCM. After the optimization, the FCM can significantly improve the detection efficiency of mobile malware. The simulation experiments show that the IBA has ...
