Abstract

An image processing apparatus that executes a plurality of processes related to a file, includes: a memory that stores a file; a processor that executes virus checking on the file. The memory stores: virus type information that associates a type of a virus detected during the virus checking with at least one of the plurality of processes; and file type information that associates a type of file with at least one of the plurality of processes, and the processor restricts one of the plurality of processes associated with the type of the detected virus, and another of the plurality of processes associated with the type of file possibly infected with the detected virus.

First claim

What is claimed is:

1. An image processing apparatus that executes a plurality of processes related to a file, the apparatus comprising:
a memory that stores a file;
a processor that executes virus checking on the file, wherein
the memory stores:
virus type information that associates a type of a virus detected during the virus checking with at least one of the plurality of processes; and
file type information that associates a type of file with at least one of the plurality of processes, and

the processor restricts one of the plurality of processes associated with the type of the detected virus, and another of the plurality of processes associated with the type of file possibly infected with the detected virus.

2. The image processing apparatus according to claim 1 , wherein
when the file infected with the detected virus has not been executed and the type of the detected virus is a type that does not tamper with the file in the memory, the processor cancels the restriction of the plurality of processes after the virus is removed.

3. The image processing apparatus according to claim 2 , wherein
the processor determines whether the file has been executed based on a log of access to the file or a history of the file stored in the memory.

4. The image processing apparatus according to claim 1 , wherein
when the type of the detected virus is a type that tampers with the file in the memory, the processor examines the file in the memory for possible infection with the detected virus.

5. The image processing apparatus according to claim 1 , wherein
the plurality of processes include a process of communicating with an external device, and
when a virus is detected in the virus checking, the processor removes the virus after restricting the process of communicating with the external device.

6. The image processing apparatus according to claim 1 , wherein
the processor notifies that the file is possibly infected with the virus.

7. The image processing apparatus according to claim 1 , wherein
the processor examines the file in the memory for possible infection with the virus using at least one of: information on the file obtained when the file was stored in the memory; information on the file at a last virus checking; information on the file at a latest usage; and information on the file at a present virus checking.

8. The image processing apparatus according to claim 7 , wherein
the information on the file at the latest usage includes information specifying a date and time of the latest usage,
the information on the file at the last virus checking includes information specifying a date and time of the last virus checking, and a checksum value of the file at the last virus checking, and
the information on the file at the present virus checking includes a checksum value of the file at the present virus checking.

9. A method of controlling an image processing apparatus that executes a plurality of processes related to a file, the method comprising:
executing virus checking on a file stored in a memory of the image processing apparatus; and
setting, as restricted processes, one of the plurality of processes associated with a type of a virus detected during the virus checking, and another of the plurality of processes associated with a type of file possibly infected with the virus detected during the virus checking.

10. The method according to claim 9 , further comprising:
when the file infected with the detected virus has not been executed and the type of the detected virus is a type that does not tamper with the file in the memory, cancelling the restriction of the plurality of processes after the virus is removed.

11. The method according to claim 10 , further comprising:
determining whether the file has been executed based on a log of access to the file, or a history of the file stored in the memory.

12. The method according to claim 9 , further comprising:
when the type of the detected virus is a type that tampers with the file in the memory, examining the file in the memory for possible infection with the detected virus.

13. The method according to claim 9 , wherein
the set restricted processes include a process of communicating with an external device, and
the method further comprises, when a virus is detected in the virus checking, removing the virus after restricting the process of communicating with the external device.

14. The method according to claim 9 , further comprising:
giving a notification of the file possibly infected with the virus.

15. The method according to claim 9 , further comprising:
examining the file in the memory for possible infection with the virus by using at least one of: information on the file obtained when the file was stored in the memory; information on the file at last virus checking; information on the file at latest usage; and information on the file at present virus checking.

16. The method according to claim 15 , wherein
the information on the file at the latest usage includes information specifying a date and time of the latest usage,
the information on the file at the last virus checking includes information specifying a date and time of the last virus checking, and a checksum value of the file at the last virus checking, and
the information on the file at the present virus checking includes a checksum value of the file at the present virus checking.

17. A non-transitory computer-readable storage medium storing a computer program comprising instructions that, when executed by a computer, cause the computer to execute the method according to claim 9 .
