软件补丁或警告等对策可以有效地帮助组织避免病毒感染问题。然而，目前传播这种反措施的战略限制了它们的效力。我们提出了一种新的方法，称为对策竞争（CMC）战略，并使用计算机模拟正式比较其相对有效性与目前正在考虑的三种防病毒策略。CMC基于这样的思想，即计算机病毒和对策通过两个独立但相互关联的复杂网络传播-病毒传播网络和对策传播网络，其中对策充当与计算机病毒竞争的物种。我们的研究结果表明，CMC是更有效的比其他策略的基础上的经验病毒数据。建议CMC减少病毒感染的大小显着时，对策传播网络的属性，有利于对策超过病毒，或当对策传播率高于病毒传播率。此外，我们的工作表明，CMC可以灵活地适应不同的不确定性，在真实的世界，使它能够被调整，比其他战略的各种情况。
Countermeasures such as software patches or warnings can be effective in helping organizations avert virus infection problems. However, current strategies for disseminating such countermeasures have limited their effectiveness. We propose a new approach, called the Countermeasure Competing (CMC) strategy, and use computer simulation to formally compare its relative effectiveness with three antivirus strategies currently under consideration. CMC is based on the idea that computer viruses and countermeasures spread through two separate but interlinked complex networks-the virus-spreading network and the countermeasure-propagation network, in which a countermeasure acts as a competing species against the computer virus. Our results show that CMC is more effective than other strategies based on the empirical virus data. The proposed CMC reduces the size of virus infection significantly when the countermeasure-propagation network has properties that favor countermeasures over viruses, or when the countermeasure-propagation rate is higher than the virus-spreading rate. In addition, our work reveals that CMC can be flexibly adapted to different uncertainties in the real world, enabling it to be tuned,to a greater variety of situations than other strategies.
