  • DEVICE AND METHOD FOR BLOCKING AUTORUN OF MALICIOUS CODE
    Publication number: 20090138969
    Abstract: A device and method for blocking autorun of a malicious code through an autorun file stored in a removable storage device are provided. A device manager monitors a connection of a removable storage device, acquires a global unique identifier of the removable storage device, and deletes an autorun file for running the malicious code from the removable storage. A registry manager determines whether a registry key for storing content of the autorun file is generated using the global unique identifier of the removable storage device and deletes the registry key. The present invention can block autorun of a malicious code stored in the removable storage device by retrieving and deleting a registry key for performing the autorun technique when a removable storage device is connected to a system.
