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 CompuClever Antivirus Plus and select Immunize this drive.

    [Note] 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”.
