Abstract:Characteristic code antivirus system can no longer meet current computer virus detection demand and will be replaced by the behavior detection method. With a brief analysis of virus abnormal behavior and an application of the state transition method to the virus behavior detection, this paper proposed the probability training based virus detection model. Implemented the virus judgment algorithm with a concrete virus probability training procedure of both single and continuous abnormal behavior, and a training procedure of virus probability threshold. The probability training based virus detection model proves to be effective with reliable case analysis and detection result verification.......
