严重声明：这个程序只是供C语言新手参考，开玩笑没关系，但如果用来做不法的事情，本人概不负责。还有，编病毒、木马去做违法的事情惩罚是很重的，你如果想学编程，编个简单的就好了，否则后果很严重。
最简单的木马 源代码以及解释
一个完整的木马系统由硬件部分，软件部分和具体连接部分组成。
(1)硬件部分：建立木马连接所必须的硬件实体。 控制端：对服务端进行远程控制的一方。 服务端：被控制端远程控制的一方。 INTERNET：控制端对服务端进行远程控制，数据传输的网络载体。
(2)软件部分：实现远程控制所必须的软件程序。 控制端程序：控制端用以远程控制服务端的程序。 木马程序：潜入服务端内部，获取其操作权限的程序。 木马配置程序：设置木马程序的端口号，触发条件，木马名称等，使其在服务端藏得更隐蔽的程序。
(3)具体连接部分：通过INTERNET在服务端和控制端之间建立一条木马通道所必须的元素。 控制端IP，服务端IP：即控制端，服务端的网络地址，也是木马进行数据传输的目的地。 控制端端口，木马端口：即控制端，服务端的数据入口，通过这个入口，数据可直达控制端程序或木马 程序。
