If you are interested in Autorun Protector 1.0, you may continue to read on.

Autorun Protector is a two way protection standalone software that prevents your PC from infecting with autorun worms and also protecting your removable device from being infected from other sources. Hence, it decreases the spread of the worms.

In addition, it also come with additional features like custom protected autorun.inf file, removing of autorun.inf & resolving drive opening issue.

You may wonder what is considered as an autorun worm? Autorun worm is a worm that infects your PC through removable device such as USB thumb drive or CD/DVD. In addition, it has a file called autorun.inf which contains code to run malicious program. If your PC does not block autorun, the autorun worm will executes once you double click the drive letter of your removable device. Microsoft Windows Operating System does not disable autorun by default.


  1. This program does not help you to clean all type of autorun worms. It is to protect your PC & Device from infecting the worms. If your PC is already infected with autorun worms, I suggest you to clean the worm first by using anti-virus program or do a clean reinstallation of operating system.
  2. Make sure you have administrative access to run most of the task below. Some task might require a restart to take effect.
  3. If you execute the program and encounter Application Error message indicating “The application failed to initialize properly (0xc0000135). Click on OK to terminate the application.”, you will need to download .NET Framework 2.0 and above in order to run this program.

Autorun Protector Main Screen


PC Protection

Autorun Protection Status

By enabling this protection, your computer will treat autorun.inf as if it does not exist. So far I think this method is the best for disabling autorun worms from infecting into your PC. Credit goes to the author Nick Brown and his colleague.

Special note: This may causes devices like PortableApps or U3 devices and CD/DVD ROMs drive to ignore the autorun program. Do not panic if you still see an Autoplay menu when you insert a removable media. To know more about the difference between autoplay and autorun, visit Microsoft webpage by clicking here.

Clear MountPoints2 Registry

The MountPoints2 registry key contains cached information about every removable device seen so far. Clearing this key might solve the problem on opening drive problem issue. Its safe to clear this registry key even though your system is not infected.

Device Protection


The list box will show you the list of drive that is active in the system. You can click the Refresh button if you have just plug in the device and the removable device will be listed inside.

File System

This will show you the file system that the selected drive uses. I recommend you to use NTFS if your device do support. It enhances the security if you create the NTFS Custom Protected autorun.inf (Read below). More info on converting your file system to NTFS, click here.

Autorun File

There will be 4 different messages displaying here.

Autorun File Message 1

This means that no autorun.inf found on the selected drive and is Safe.

You may wish to click the Create button to create a protected autorun.inf. By doing so, the program will generate a custom autorun.inf into the drive, if your drive file system is NTFS, it will add an extra layer of security.

Autorun File Message 2

This means that autorun.inf is found in the selected drive and this copy of the autorun.inf is not generated from Autorun Protector program.

If your drive does not come with any special autorun utility like PortableApps or U3 Apps etc, I will strongly advise you to click the Remove button. After that, you can click the Create button if you wish to protect with the program custom copy of autorun.inf.

Autorun File Message 3

This means that the selected drive is protected by Autorun Protector custom autorun.inf and it is Safe. Usually this is for non NTFS File System.

Autorun File Message 4

This means that the selected drive is protected by Autorun Protected custom autorun.inf and it is Safe. You will see this message if you protect your NTFS device using Autorun Protector.

    Hi Raymond…Great work.


    I have a query regarding the custom protected autorun.inf
    If I create it on my usb drive and then take the drive to another machine which has some other AutoProtector kind of program to scan for autorun.inf,then won’t this custom autorun.inf be detected as suspicious in that machine by that other program?

    • 2. Raymond  |  May 22, 2009 at 9:46 pm

      Hi Samanta, thanks for using Autorun Protector 🙂

      It depends on what kind of autorun protection software they have. They might mark this file as danger because if an external device comes with an autorun.inf file, it might be a potential risk to be a worm. However, for this case, it is not. As this is a custom protected autorun.inf to protect other PC from infecting your device (overwrite your protected autorun.inf) easily.

      Some thumbdrive brand like U3 or Toshiba or even some 3rd party software like portableapps will include an additional utility that also make use of their own autorun.inf. Some protection software might already mark these autorun.inf as safe file, so it might not trigger an alert.

      To make sure that you are still using Autorun Protector Custom Protected autorun.inf, simply just run the Autorun Protector and select your drive under Device Protection and look for the Autorun File status.

    yup it can be used in Windows XP with .NET Framework 2.0 and above installed.

    If you can start the program successfully without any error code, means that .NET Framework is already installed in your system.
