A method to detect unknown computer virus and its implementation

摘要

The spread of computer virus via E-mail is a social problem. In some virus detection system with pattern matching mechanism, they can detect die virus as long as they have pattern files corresponding to that. However, such a system can not detect an unknown virus. In this paper, we propose a system to detect unknown virus. The system receives all E-mail in user's place. That opens and executes the mail with attached file and watches its behavior against Operating System etc. in order to detect the unknown virus.
