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.

Claims

1. A method for preventing virus infections via the use of a removable storage device configured to connect to a computer, comprising:

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 to cause the computer to identify the removable storage device as a writable device after the antivirus program is launched on the computer.

2. The method of claim 1, further comprising initiating the gathering step in response to a command requesting to identify the removable storage device.

3. The method of claim 1, wherein the first set of information comprises information associated with a virtual read-only partition and information associated with a storage partition, wherein both the virtual read-only partition and the storage partition belong to a storage area in the removable storage device.

4. The method of claim 1, wherein the second set of information includes information associated with a virtual read-only partition in the removable storage device but excludes information associated with a storage partition in the removable storage device.

5. The method of claim 1, wherein the third set of information includes information associated with a storage partition in the removable storage device but excludes information associated with a virtual read-only partition in the removable storage device.

6. The method of claim 3, wherein the third set of information is the first set of information.

7. The method of claim 1, further comprising initiating the accessing step in response to a command requesting to access the antivirus program.

8. A computer-readable medium containing a sequence of instructions, which when executed by a computing device in a removable storage device, causes the computing device to:

gather a first set of information associated with the removable storage device;

process the first set of information to generate a second set of information also associated with the removable storage device;

send the second set of information to a computer coupled to the removable storage device to cause the computer to identify the removable storage device as a read-only device;

access an antivirus program stored in the removable storage device and cause the antivirus program to be launched on the computer; and

send a third set of information to the computer to cause the computer to identify the removable storage device as a writable device after the antivirus program is launched on the computer.

9. The computer-readable medium of claim 8, further containing a sequence of instructions, which when executed by the computing device, causes the computing device to gather the first set of information in response to receiving a command requesting for information to identify the removable storage device.

10. The computer-readable medium of claim 8, further containing a sequence of instructions, which when executed by the computing device, causes the computing device to gather the first set of information comprising information associated with a virtual read-only partition and information associated with a storage partition, wherein both the virtual read-only partition and the storage partition belong to a storage area in the removable storage device.

11. The computer-readable medium of claim 8, wherein the second set of information includes information associated with a virtual read-only partition in the removable storage device but excludes information associated with a storage partition also in the removable storage device.

12. The computer-readable medium of claim 8, wherein the third set of information includes information associated with a storage partition in the removable storage device but excludes information associated with a virtual read-only partition in the removable storage device.

13. The computer-readable medium of claim 10, wherein the third set of information is the first set of information.

14. The computer-readable medium of claim 8, further containing a sequence of instructions, which when executed by the computing device, causes the computing device to access the antivirus program in response to a command requesting to access the antivirus program.

15. A removable storage device, comprising:

a storage area including a virtual read-only partition and a storage partition; and

a computing device, coupled to the storage area, further including a system memory, and a processing unit, wherein the processing unit is configured to

gather a first set of information associated with the removable storage device,

process the first set of information to generate a second set of information also associated with the removable storage device,

send the second set of information to a computer coupled to the removable storage device to cause the computer to identify the removable storage device as a read-only device,

access an antivirus program stored in the removable storage device and cause the antivirus program to be launched on the computer, and

send a third set of information to the computer to cause the computer to identify the removable storage device as a writable device after the antivirus program is launched on the computer.

16. The removable storage device of claim 15, wherein the processing unit is further configured to gather the first set of information in response to receiving a command requesting for information to identify the removable storage device.

17. The removable storage device of claim 15, wherein the second set of information includes information associated with the virtual read-only partition but excludes information associated with the storage partition.

18. The removable storage device of claim 15, wherein the third set of information includes information associated with the storage partition but excludes information associated with the virtual read-only partition.

19. The removable storage device of claim 15, wherein the third set of information is the first set of information.

20. The removable storage device of claim 15, wherein the processing unit is further configured to access the antivirus program in response to receiving a command requesting to access the antivirus program.
