BitDefender USB Immunizer 2.0.1.8



BitDefender USB ImmunizerBitdefender USB Immunizer protects Removable Drives from Autorun-Based Attacks. It is a simple tool that can reduce that chance of your USB flash drive becoming infected by autorun-based malware. Use BitDefender USB Immunizer, though, and the program will create an Autorun.inf folder on your PC, which in turn contains a number of other files. If malware tries to create an Autorun.inf file on the drive, then the operation will fail (you can’t have an \Autorun.inf file if there’s already a folder there with the same name). This doesn’t offer a complete guarantee of safety, as the malware could delete the folder, but most won’t even attempt to do this and so the Immunizer does offer useful protection. As a bonus, the tool also offers a way to turn Autorun off for removable media (though not CD/ DVD drives), which will prevent USB-based malware from executing automatically, even if Immunizer fails. There’s no complexity to it, no drives to select, just click the “Off” button and your system will be just a little safer.
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.
Under normal circumstances this can happen very easily. All you need to do is plug your drive into an infected PC, and the malware will copy itself to the device, adding a custom autorun.inf file. When you next connect the drive to a system where autorun is enabled, the malware will be launched, and that PC will become infected, too.
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.
