Image forming apparatus, server, control program of image forming apparatus, and control program of server

An image forming apparatus that communicates with a server, the image forming apparatus comprising:

• a storage that stores a virus pattern file;
• and
• a hardware processor,
• wherein the hardware processor discriminates, in a case where a transition is made from a state in which power supply to the hardware processor is interrupted to a state in which the power supply to the hardware processor is made, whether the virus pattern file stored in the storage is a latest version, in communication with the server,
• wherein the hardware processor includes an updater that updates, in a case where the hardware processor discriminates that the virus pattern file stored in the storage is not the latest version, the virus pattern file stored in the storage to a virus pattern file acquired from the server, and
• wherein the hardware processor executes an external task that is a task of making access outside the image forming apparatus, after the update by the updater.

A server that communicates with an image forming apparatus, the server comprising:

• a storage that stores a virus pattern file, the storage further storing an update history of a virus pattern file retained by the image forming apparatus;
• a hardware processor that discriminates whether the virus pattern file retained by the image forming apparatus is a latest version, based on the update history of the virus pattern file retained by the image forming apparatus;
• and
• an update requester that requests, in a case where the hardware processor discriminates that the virus pattern file retained by the image forming apparatus is not the latest version, the image forming apparatus to update the virus pattern file retained by the image forming apparatus to the virus pattern file stored in the storage,
• wherein the hardware processor discriminates, in the case where the hardware processor discriminates that the virus pattern file retained by the image forming apparatus is not the latest version, whether the image forming apparatus is in a sleep mode,
• wherein the server further comprises a recoverer that causes, in a case where the hardware processor discriminates that the image forming apparatus is in the sleep mode, the image forming apparatus to recover from the sleep mode, and
• wherein the update requester requests the image forming apparatus to update the virus pattern file retained by the image forming apparatus, after the recovery by the recoverer.

A non-transitory recording medium storing a computer readable control program of an image forming apparatus that communicates with a server, the image forming apparatus including a storage that stores a virus pattern file and a hardware processor, the control program causing a computer to perform:

• discriminating, in a case where a transition is made from a state in which power supply to the hardware processor is interrupted to a state in which the power supply to the hardware processor is made, whether the virus pattern file stored in the storage is a latest version, in communication with the server;
• updating, in a case where it is discriminated that the virus pattern file stored in the storage is not the latest version in the discrimination, the virus pattern file stored in the storage to a virus pattern file acquired from the server;
• discriminating whether a job accepted is a first type of job using data acquired from outside the image forming apparatus or a second type of job using data generated inside the image forming apparatus;
• and
• executing the first type of job after the update.

A non-transitory recording medium storing a computer readable control program of a server that communicates with an image forming apparatus, the server including a storage that stores a virus pattern file, the storage further storing an update history of a virus pattern file retained by the image forming apparatus, the control program causing a computer to perform:

• discriminating whether the virus pattern file retained by the image forming apparatus is a latest version, based on the update history of the virus pattern file retained by the image forming apparatus;
• and
• requesting, in a case where it is discriminated that the virus pattern file retained by the image forming apparatus is not the latest version in the discrimination, the image forming apparatus to update the virus pattern file retained by the image forming apparatus to the virus pattern file stored in the storage,
• wherein the computer discriminates, in the case where the computer discriminates that the virus pattern file retained by the image forming apparatus is not the latest version, whether the image forming apparatus is in a sleep mode,
• wherein the server further includes a recoverer that causes, in a case where the computer discriminates that the image forming apparatus is in the sleep mode, the image forming apparatus to recover from the sleep mode, and
• wherein the update requester requests the image forming apparatus to update the virus pattern file retained by the image forming apparatus, after the recovery by the recoverer.
