英文摘要：

The characteristics of computer virus propagation attached on e-mail are studied. The model of computer virus epidemic is constructed, and the evolving process of virus spreading is simulated on the China Education Network. By changing infection source and adjusting infecting rate and recovering rate, some good strategies of control the spreading of virus on complex network are proposed.
