  • Publication number: 20090113128
    Abstract: A method and system for preventing virus infections via the use of a removable storage device are described. Specifically, one embodiment of the present invention sets forth a method, which includes the steps of gathering a first set of information associated with the removable storage device, processing the first set of information to generate a second set of information also associated with the removable storage device, sending the second set of information to the computer to cause the computer to identify the removable storage device as a read-only device, accessing an antivirus program stored in the removable storage device and causing the antivirus program to be launched on the computer, and sending a third set of information to the computer after the antivirus program is launched on the computer to cause the computer to identify the removable storage device as a writable device.
