摘要： 为改进计算机系统及网络的安全性和可信度，提出一种带有用户意识的计算机多病毒传播模型。综合考虑人为因素和客观因素对病毒传播的影响，采用稳定性分析和实验仿真的方法，在理论上证明无病毒平衡态是全局稳定的，地方病平衡态是局部渐进稳定的。实验结果表明，在该模型中，通过提高用户意识可以有效地控制计算机病毒的传播。

Abstract: In order to improve the security and reliability of computer systems and networks, this paper proposes an improved computer multi-virus propagation model with user awareness, and the influence of both human and objective factors is comprehensively considered. Furthermore, stability analysis and experimental simulation are adopted, that virus-free equilibrium is globally stable and virus-endemic equilibrium is locally asymptotically stable are proved. Simulation results show that in the model proposed in this paper the propagation of computer viruses can be effectively controlled by improving user awareness and reducing the frequency of new virus’s appearance.

Key words: multi-virus propagation model, user awareness, globally stable, locally stable, equilibrium point
