1. I will explain how to create a Free USB Antivirus, using the
windows notepad and a few little scripts, this Free USB
Antivirus is very powerful against autorun.inf virus, and it
takes no time to create and no time to run.
If you are at good command of dos and batch files you
can customize it.
I want to warn you to be careful when using this procedure, because you may loose data on your hard disk or
usb memory device, and I am not going take any
responsibility of any damage of your data.
Step 1:
Open your notepad or any text editor
Step 2:
Type the exact text
@ echo off
del d:\*.inf
@ echo file deleted or no file exists
pause
Explanation:
@ echo off
is a dos command that makes the system provides no confirmation
messages
del d:\*.inf
“del” is the command that deletes the desired file from the drive
“d:”
which “d:” is your usb drive letter
and you can change it as you wish
“*.inf” is the file that must be deleted
Step 3:
Save the file giving the extension bat to the created file so it should
be like that
mysimpleantivirus.bat
-3-
Step 4:
Test your simple antivirus by creating a dummy autorun.inf file on
your usb drive.
When you double click the file mysimpleantivirus.bat it will delete
the autorun.inf
Now you have added 50% protection to your system for Free
Congratulations!!
You have created your own Free USB Antivirus
