摘要：The influence of the changes about the number of the nodes with different states by the external factors is not considered in the traditional model. So, traditional models are not suitable for the cloud network which is dynamic. A virus propagation model of computer, HSIR propagation model, whish is suitable for the cloud environment is proposed in this paper. The model considers the dynamic changes of the cloud environment, the implementation of the immunization strategy and the time difference between the virus spread and the implementation of the immunization strategy. Additionally, the balance point of the HSIR model is found and the stability of the balance point is proved by the mathematical theory. The HSIR virus propagation model can describe the process of the virus propagation in the cloud environment more realistic
