Many computer viruses spread via electronic mail, making use of computer users' email address books as a source for email addresses of new victims. These address books form a directed social network of connections between individuals over which the virus spreads. Here we investigate empirically the structure of this network using data drawn from a large computer installation, and discuss the implications of this structure for the understanding and prevention of computer virus epidemics.
许多计算机病毒通过电子邮件传播，利用计算机用户的电子邮件地址簿作为新受害者电子邮件地址的来源。这些地址簿形成了一个个体之间的有向社交网络连接，病毒通过这个网络传播。在这里，我们使用从一个大型计算机设施中提取的数据，对这个网络的结构进行实证研究，并讨论这种结构对理解和预防计算机病毒传播的影响。
