  • Publication number: 20120222120
    Abstract: A malware detection method and a mobile terminal realizing the same are provided. The method monitors execution of applications on the mobile terminal, notifies a user of perceived malicious behavior and guides handling of a detected malicious application. The malware detection method includes extracting, when a platform Application Programming Interface (API) is called by an application, an action of the application from the platform API, determining, when the extracted action is a preset trigger action, whether the application is a malware program by comparing the extracted action with a malware pattern file, and outputting, when the application is a malware program, an alert message.
