When computer virus wide spreads in the world nowadays, anti-virus needs to improve their identifying methods to enhance the performance. In this paper, we introduce a new method to diagnose computer virus. First, we analyse the characteristics of viral data type to define virus classes through object-oriented methods. Second, we study the machine learnning mechanism for each virus class. Finally, we apply these learning forms to a data processing stage of a machine learning anti-virus expert system. The experimentation results show that the machine learning approach is suitable for anti-virus to identify the computer virus. This approach also gives a new aspect of anti-virus technology. | ’ Tap ch´ Tin hoc v` Diˆu khiˆn hoc, , (2008), 32–41 ı a ` e e . . . . ’ ´ ˆ ´ ˆ ´ ´ INH CO CHE MAY HOC CHAN DOAN VIRUS MAY T´ . . . ´ ` ˆ ˆ HOANG KIEM1 , TRU O NG MINH NHAT QUANG2 . 1 Dai hoc Cˆng nghˆ Thˆng tin, DHQG ` o e o . . . 2 Trung tˆm D`o tao Dai hoc Tai ch´.c Cˆn Tho. a a . u ` a . . . Abstract. When computer virus wide spreads in the world nowadays, anti-virus needs to improve their identifying methods to enhance the performance. In this paper, we introduce a new method to diagnose computer virus. First, we analyse the characteristics of viral data type to define virus classes through object-oriented methods. Second, we study the machine learnning mechanism for each virus class. Finally, we apply these learning forms to a data processing stage of a machine learning anti-virus expert system. The experimentation results show that the machine learning approach is suitable for anti-virus to identify the computer virus. This approach also gives a new aspect of anti-virus technology. ´ ´ ´ ´ T´m t˘t.
