Network Virus Propagation Model Based on Effects of Removing Time and User Vigilance

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. This paper investigates 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.
