All about autorun.inf

It is been long i thought of blogging about this topic, finally i am able to do this now.

What is this ?

I guess very few might have knowledge about this file, this is the file you most often see in the cd's(compact disc) home directory.You might have seen, when you insert cd into the drive , it gets auto started with some program,or it will open some default file , basically some sort of task is performed when cd is inserted.You might have wondered how this happened.Its all the magic of this autorun.inf file.

This is a some sort of script file ,which tells windows what to do upon the opening of folder in which it is located.which is type of initialization file ,which tells what actions to perform when the folder is opened.

We can do lot of things with it.You can make the windows set some background , when folder opens , and many more.This windows oses feature has made the viruses a way to spread themselves .Most often it is used by viruses ;).

Sometimes you might have seen , you try to open a drive/folder.It fails to
open.Its because of this autorun.inf.

How to locate and remove it ?
This file is always hidden in the folder.you can see this file in the root
folder of usb stick.You can use Dir /a to find that file from command line.Viruses make an entry in it , to run when the folder is opened.Just open that file from command line and see some malicious code has made an entry in it.If so you can safely delete this file.
