A novel method based on support vector machine (SVM) is proposed for detecting computer virus. By utilizing SVM, the generalizing ability of virus detection system is still good even the sample dataset size is small. First, the research progress of computer virus detection is recalled and algorithm of SVM taxonomy is introduced. Then the model of a virus detection system based on SVM and virus detection engine are presented respectively. An experiment using system API function call trace is given to illustrate the performance of this model. Finally, comparison of detection ability between the above detection method and other is given. It is found that the detection system based on SVM needs less priori knowledge than other methods and can shorten the training time under the same detection performance condition.
