Internet worms pose a serious threat to the Internet security. In order to effectively defend against Internet worms, this paper proposes a novel epidemic e-SEIQV model with quarantine and vaccination. Using this e-SEIQV model, the authors obtain the basic reproduction number for determining whether the worm dies out completely. The global stability of the worm-free equilibrium and the local stability of endemic equilibrium are proved and determined by the basic reproduction number. Besides the impact of different parameters, this model is studied.
