Mobile information terminal and virus detection and treatment service method of the mobile information terminal {Mobile Communication Terminal And Computer Virus Detection And Cure Service Method In The Mobile Communication Terminal}

The present invention relates to a virus detection and treatment service method in a portable information terminal, and more particularly, to a portable information terminal having a connection function to a wireless communication network such as a mobile communication network (CDMA) and a wireless local area network (Wireless-LAN). The present invention relates to a method for efficiently detecting a computer virus and providing a service for treating a detected virus.

At present, virus detection and treatment for general desktop personal computers is already well known. The virus detection and treatment service for a general desktop personal computer is composed of virus detection and treatment software running on a personal computer and a server system built by a virus detection and treatment engine manufacturer. The user's desktop personal computer and the vendor's server system are connected via a regular wired Internet.

In a virus detection and treatment service for a general desktop personal computer, a user purchases virus detection and treatment software and installs it on his personal computer to perform virus detection and treatment functions. The engine for virus detection is automatically executed when the personal computer is initialized to detect when a recognizable virus penetrates. In addition, if a virus is detected, the user is notified of the operation of the treatment function, and accordingly, the treatment function is operated to treat it.

That is, in the virus detection and treatment service for a general desktop personal computer, all functions related to virus detection and treatment must be present in the personal computer, and the virus detection and treatment function is performed using only the functions installed in the personal computer. To do this, you must have enough storage memory to store all of the files involved and the working memory required to operate these files. The average desktop personal computer has enough memory and hard disk, so there is no problem with this method.

In addition, the virus detection and repair service for existing desktop personal computers updates the virus detection and repair files without forgetting the user so that the virus can be detected and repaired after purchasing the virus detection and repair software. Should be. In other words, the update process must be done entirely by the user. Therefore, if the user is indifferent to such a problem, the user may not be able to cope with the new virus even after purchasing and installing the software.

Virus detection and treatment services for general desktop personal computers mentioned so far are portable information terminals that are relatively scarce in resources such as memory and storage space (herein, portable information terminals are PDAs (Personal Digital Assistants), smart phones and web pads, etc.). ] Is a problem to apply as it is. Because of the lack of storage space, there is a problem in storing all files and information related to virus detection and treatment in the portable information terminal. Therefore, in the case of a portable information terminal, a new method of virus treatment that can take full advantage of a radio access function and a synchronization function with a personal computer should be devised while considering relatively scarce resources.

In addition, since the portable information terminal does not have a disk, a nonvolatile memory such as flash memory is used instead, and the operating system software is basically loaded there. In general, commercial applications are stored in volatile memory such as DRAM. In this case, when the battery of the portable information terminal is discharged, information on general commercial applications is lost and must be newly installed. If the virus detection engine is installed in the same way as a general commercial application, it is lost when the battery is discharged. If the user does not recognize it and does not reinstall it, the virus detection function cannot be used. Therefore, there is a need for a service method in which a virus detection engine is stored in a nonvolatile memory along with operating system software through a registration process to an operating system, or at least reinstalled when the virus detection engine is lost. In general, there is room for nonvolatile memory because there is free space in addition to the space used by the operating system software. The operating system has a function to store and execute an engine for virus detection at a specific location in the nonvolatile memory. Including in software can solve the problem of battery loss.

In connection with the above problem, there is a need for a new method for solving a problem related to function update, which is left as a user's responsibility, in a more favorable form for the user. The portable information terminal can be connected to a mobile communication network such as CDMA or a wireless local area network (Wireless-LAN) using a wireless access function, and can also be connected to a personal computer using a synchronization function with a personal computer. Therefore, it is necessary to use a service method that can make full use of these functions to provide automatic update of virus detection function.
