4.15. USB Immunizer
The Autorun feature built into Windows operating systems is a very useful
tool that allows devices 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 threats to automatically
launch and infiltrate your device 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 threats ever again. Once an USB
device is immunized, threats can no longer configure it to run a certain app
when the device is connected to a device running Windows.
To immunize an USB device:
1. Connect the flash drive to your device.
2. Browse your device 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 threat will appear instead of the Immunize
option.
To prevent your device from launching threats from unimmunized USB
devices, disable the media autorun feature. For more information, refer to
Using automatic vulnerability monitoring (p. 112).
