24. USB Immunizer

The Autorun feature built into Windows operating systems is a very useful tool that

allows computers to automatically execute a file from media connected to it. For

example, software installations can start automatically when a CD is inserted into

the optical drive.

Unfortunately, this feature can also be used by malware to automatically launch

and infiltrate your computer from rewritable media such as USB flash drives and

memory cards connected through card readers. Numerous Autorun based attacks

have been created in recent years.

With USB Immunizer you can prevent any NTFS, FAT32 or FAT formatted flash drive

from automatically executing malware ever again. Once an USB device is immunized,

malware can no longer configure it to run a certain application when the device is

connected to a computer running Windows.

To immunize an USB device, follow these steps:

1. Connect the flash drive to your computer.

2. Browse your computer to locate the removable storage device and right-click its

icon.

3. In the contextual menu, point to Bitdefender and select Immunize this drive.

Note

If the drive has already been immunized, the message The USB device is

protected against autorun-based malware will appear instead of the Immunize

option.

To prevent your computer from launching malware from unimmunized USB devices,

disable the media autorun feature. For more information, please refer to “Using

automatic vulnerability monitoring” (p. 90).
