Abstract：This paper breaks the uniformity and symmetry constraints of traditional virus propagation model,that the probability of infective node infect healthy node is decided in accordance with its neighbor node degree, and health nodes whose level be susceptible to infection according to their degree of difference with the infected nodes, considering the combined effect of both on the behavior of the spread of the virus. The impact on the virus behavior is verified by changing the parameters through the introduction of the role of those two factors. The simulation results show that the directionality of the infected node infection preferences and propagationbehavior does affect the speed of virusspreading, Finally, the spread of models given about the spread of the virus to speed up and slow down.
