在现实中，外部计算机，特别是外部受感染的计算机连接到互联网。基于这一合理假设，建立了一种全新的计算机病毒传播模型。与以往的所有模型不同，该模型将外部计算机视为一个单独的舱室进行研究。通过定性分析发现：(1)该模型存在唯一的(病毒式)平衡点；(2)该平衡点是全局渐近稳定的。进一步的研究表明，通过采取有效措施，可以将受感染的计算机数量控制在可接受的阈值以下。
In reality, the external computers, in particular, external infected computers are connected to the Internet. Based on this reasonable assumption, a new computer virus propagation model is established. Different from all the previous models, this model regards the external computers as a single compartment to study. Through a qualitative analysis, it is found that (1) this model possesses a unique (viral) equilibrium, and (2) this equilibrium is globally asymptotically stable. Further study shows that, by taking effective measures, the number of infected computers can be made below an acceptable threshold.
