Network virus propagation is influenced by various factors and some of them are neglected in most of the existed models. So, mathematical model of network virus propagation is simplified. In fact, many factors are very important during the virus propagation. In this paper, the authors investigate epidemiological models to reason about email virus propagation. The paper extended the classical virus propagation model SEIR for incorporating two new parameters: user vigilance and removing time. They show that these parameters greatly influence the virus propagation.
