itDefender USB Immunizer is a software application built specifically for helping users protect their USB flash drives against infections with autorun-based malware.

By default, the removable storage devices store an autorun.ini file which usually is infected with different types of malware. This is why, you need dedicated tools like BitDefender USB Immunizer to keep your PC protected against malware.

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry. You can copy it on any USB flash drive or other devices, and take it with you whenever you need to immunize your USB storage devices on the breeze.

BitDefender USB Immunizer sports a simplistic interface that allows users to perform most operations with minimum effort.

Basically, it proves to be extremely easy to work with this tool, as with just one click on the red program’s icon, you can activate the immunizing mode. At the end of the task, the program informs you if the USB flash drive has been immunized successfully.

What’s more, you can activate the automatic feature for making the program immunize all USB storage devices that are connected to your computer.

During our testing we have noticed that the tool immunizes USB flash drives quickly and with minimum effort. It manages to remain light on the system resource, so it doesn’t hamper computer performance, nor interfere with other programs’ functionality.

All things considered, BitDefender USB Immunizer makes the entire process seem nothing but a piece of cake. It is suitable for all types of users, regardless of their experience level.

For years, Autorun-based malware has been atop of the worldwide e-threat landscape, with notorious representatives such as Trojan.AutorunInf, the Conficker worm (Win32.Worm.Downadup) or Worm.Autorun.VHD.

Introduced back in the Windows XP era to facilitate software installations from CD-ROM media for non-technical computer users, the Autorun feature has rapidly become the infection vector of choice for cyber-criminals.

The USB immunizer is Bitdefender's response to this growing issue. This small utility is divided in two sections.

The Immunize option allows you to immunize your USB storage device or SD card against infections with autorun-based malware. Even if your storage device has been plugged into an infected computer, the piece of malware will be unable to create its autorun.inf file, thus annihilating any chance of auto-launching itself.

The Immunize Computer slider allows you to toggle the autorun feature On or Off for any removable media (except for CD/DVD-ROM devices). If you accidentally plug in an infected USB drive that has not been immunized, the computer will not auto-execute the piece of malware located on the USB storage device.

Back in the days of the floppy drive, disks where the most common way of spreading viruses and malware. The Internet has taken over, and floppy drives are long gone.

They have been replaced by removable drives and optical discs, which are also capable of spreading malware, and while they are not the number one attack vector anymore, they still pose a threat.

Autorun attacks, like that by the Stuxnet worm, have become a common attack form. That common, that Microsoft has started to patch the autorun functionality in Windows.

Panda Security released USB Vaccine a while ago which offered to vaccinate a computer or USB drive to protect the computer from autorun based attacks.

Bitdefender, another popular security developer, has now released a similar program called Bitdefender Immunizer.

The program offers the same functionality as Panda USB Vaccine. Users can either immunize the computer as a whole, or immunize a connected removable drive.

The product page describes what happens if you immunize an USB drive:

The Immunize option allows you to immunize your USB storage device or SD card against infections with autorun-based malware. Even if your storage device has been plugged into an infected computer, the piece of malware will be unable to create its autorun.inf file, thus annihilating any chance of auto-launching itself.

This basically blocks the creation of autorun.inf files on immunized USB devices.

The computer immunization has the following effect:

The Immunize Computer slider allows you to toggle the autorun feature On or Off for any removable media (except for CD/DVD-ROM devices). If you accidentally plug in an infected USB drive that has not been immunized, the computer will not auto-execute the piece of malware located on the USB storage device.

The security patch linked above seems to have the same effect as the Immunize Computer option.

It has to be noted that immunizing removable devices or computers does not protect the system if the user executes malicious software on the device or computer manually. It only protects against autorun-based attack forms that require no user interaction.

Interested users can download USB Immunizer from the Bitdefender Labs website.

Update: Bastik has posted his findings in the comments, they are important and need to be mentioned in the article. Thanks Bastik for the helpful insight.

The tool does not offer to remove the protection from drives that it has immunized. To unprotect a drive you need to display hidden files in Windows and hidden system files. This can be done via Tools > Folder Options > View in Windows Explorer. You then need to delete the folder autorun.ini on the drive.

The tool displays an email prompt on exit with no apparent option to close it. Just click the ok button without entering an email address to close the program for good.

The BitDefender USB Immunizer is a tool that works for any USB device and immuzes it by preventing a malicious autorun.inf file (a file that gets executed once a USB device is plugged in) to be created by viruses or worms. This nullifies any threats for the viruses or worms to be executed in the machine where the USB device is plugged in.

I frequently found these threats whenever I plug a friend’s USB device into my computer. Thankfully I always have a good commercial antivirus solution installed in my machine so the autorun threat was always found and removed. Some of us may not be that lucky, though – which is why you might need to run this USB immunizer.

Some of the threats that create these dangerous autorun.inf are Trojan.AutorunInf, the Conficker worm (Win32.Worm.Downadup), Worm.Autorun.VHD and the Stuxnet worm. The USB Immunizer tool is free to download and it works by shielding your USB device from creating an autorun.inf file, removing the threat completely and pre-emptively.

The tool also allows you to toggle the Autorun feature on or off on any USB drives (Flash drives or External hard drives). This way, you’ll never receive angry statements from a friend because  your device is trying to wreak havoc to his/her computer :)

Security is always a hot issue in the world of technology, but sometimes you don’t have the luxury of being totally safe. For example, when it comes to mobile USB storage, like a USB flash drive, it can be difficult to discern how secure the device actually is. In fact, some of the biggest security threats have to do with autorun based software, and Windows can even execute an autorun when you plug in an external device. A lot of premium virus software allows you to scan external drives for malicious content, but most of the free programs out there do not. BitDefender USB Immunizer is a free security tool that will prevent autorun based threats and immunize external devices.

What is it and what does it do

BitDefender USB Immunizer will run in the background and protect your computer from any external threats. As soon as you plug in a USB drive, it will automatically scan and immunize the device. If you unknowingly connect an infected drive, then USB Immunizer will prevent any auto-run malware or software from starting and doing damage to the target machine.

Take note BitDefender USB Immunizer is not a malware detector or remover. It simply prevents malware from autorunning.

Pros

  • Extremely lightweight and runs in the background, only uses 10MB of RAM
  • Requires UAC (User Account Control) permissions in order to run
  • Available in a single executable and fully portable, weighing in at just over 3MB
  • Prevents the autorun process from starting whenever a USB drive is plugged into the target system
  • Can immunize a USB drive manually or automatically thus preventing any future issues

Cons

  • After a drive has been immunized the resulting autorun.inf folder cannot be deleted or altered within the Windows operating system (the drive can be formatted, however)
  • Once immunized the Windows autorun menu will no longer appear when using the affected drive
  • Does not work with some large size USB drives (typically external hard drives) because sometimes they are recognized by Windows as a local storage drive
  • Not much documentation on the application, there is a remarkably short Q&A guide
  • Automatically detects language, but this could be a problem if the application doesn’t recognize your region settings
  • Once a drive has been immunized a small pop-up ad appears for BitDefender’s AntiVirus Suite

As you already know by now, BitDefender USB Immunizer is a free security tool that runs in the background and protects your system from infected USB drives. There are essentially two parts to the tool: it stops any potential harmful software from running automatically, and it immunizes any external USB devices plugged into the system.

There are lots of well documented infections that make excellent use of the autorun feature in Windows. For example, the 2008 Conficker worm infected millions of computers thanks to the Windows autorun process- among other things.

The first part of USB Immunizer essentially disables the Windows autorun process by preventing the operating system from running the autorun.inf file. This means any time you plug in a USB device you will no longer see the usual Windows autorun menu. Instead, you will have to open the drive manually in order to access the stored content. So, even if the drive has not been immunized yet, the BitDefender USB tool will prevent anything from running as long as the tool is active in the background.

The second part of the software immunizes the device by replacing the autorun.inf file with a reputable one that cannot be altered in any way, by any program. In fact, the new autorun file cannot be deleted or overwritten, unless the drive itself is formatted or used outside of the Windows operating system. In order to get your drive back the developers even suggest connecting the device to a Linux or Mac OS X based system in order to remove the altered autorun.inf file.

What the immunizer actually does, is change the autorun.inf file into a folder of the same name. Inside that new folder, USB Immunizer places several files that inherently prevent any autorun processes from running. Keep in mind, the only way you can see these new files is if you have changed the Windows settings to show hidden files and folders (this can be done through the Windows Control Panel).

There’s only one option in the application settings, which can enable or disable automatic immunization for connected devices. As it stands, you have to tell the program to immunize your drive manually- unless of course, you enable the auto setting.

BitDefender USB Immunizer is a multi-language program, but it detects your region automatically and adjusts the app to reflect the appropriate language settings. Unfortunately, if your region is not recognized by the program then it will default to English.

BitDefender requires utterly no installation and runs just from a single executable file- which means it’s also portable. Furthermore, while running in the background, it uses just under 10MB of RAM (9,148K).

Conclusion and download link

It’s always better to be safe than sorry. If you’re like me, then you probably carry a single flash drive around with some pretty valuable files on it. The flash drive I am referring to is tremendously helpful because it allows me to transfer my work between several computers and to take my schoolwork home with me and vice versa. Unfortunately, that particular drive is being used in a lot of different computers- some of which can even be infected. My virus software does a fantastic job at scanning my local storage drives, but it cannot stop virus infections via autorun. BitDefender USB Immunizer doesn’t do any malware scanning itself, but it does help prevent autorun infections. It runs silently in the background and uses only 10MB of RAM. That’s not bad at all considering the added layer of security it provides. Unfortunately, the Windows autorun menu no longer works when I plug in my drive, but that’s okay, it’s a sacrifice I’m willing to make in order to stay protected. BitDefender USB Immunizer is totally free, and it’s certainly worth the download.

BitDefender USB Immunizer can help you prevent those viruses that are automatically spread from autorun files on USB storage devices. The program is actually very small and portable, which means that it does not require to be installed on your system. While running, it will hide on the System Tray from where it can automatically immunize all USB storage devices you insert, provided you activate the corresponding option.

It has a very intuitive interface with a nice visual design. Actually, its operation could not be made any easier; because the program automatically detects the devices you insert and gives you the choice to immunize them or does it without even asking according to your preferences. What the program actually does is to create or replace the autorun.inf file on the drive so that viruses cannot use this means of propagation. In addition, it can also detect this type of threats before they can infect your computer.

In general, BitDefender USB Immunizer has the advantage of being small and simple-to-use. However, it is far from being a complete solution for antivirus protection, as it cannot scan the drive for other types of viruses. Similarly, it cannot deactivate the AutoPlay feature in Windows or run as a system service. Other AV software can do what BitDefender USB Immunizer does and a lot more, so if you have installed another similar program, you had better check its features before installing this tool so that you can avoid redundant actions.
