Referring to the process of FIG. 7 in more detail, when the administrator of the administrator server transmits the virus check schedule to the client IP through the TCP protocol, the socket of the waiting client terminal receives this, analyzes the command, and the virus Save the check schedule to your registry. If the schedule set by the administrator and the system time of the client terminal coincide, the antivirus program is automatically run on its own computer and virus check and prevention function is performed.

In addition, the virus check schedule is stored in the registry and transmitted by the server upon request, so that the information of the administrator server and the information of the client terminal can be compared to determine whether the virus is actually executed. When the administrator of the administrator server sends the execution command of the vaccine program to the corresponding client terminal, the schedule is transmitted along with the basic information of the vaccine program. The client terminal receiving the command searches the registry according to the corresponding information, and if the vaccine program is installed, executes the vaccine. If the vaccine is not installed on the client terminal, the information is sent to the administrator server that is not installed, and the administrator server distributes the vaccine to the client according to the contents (license check), installs and executes it.

In addition, if the program manager manages the vaccine program managed at a certain location in a batch, the above function may be performed by storing the location in the manager server and transmitting the location information.

Although not shown, using the embodiments of the present invention it is possible to create a remote report. That is, if the administrator searches the DB stored by classifying the packets transmitted by the client terminals under a certain condition, the space writes the SQL internally to the condition set by the administrator and inquires the SQL statement to the relevant DB engine. The results can be loaded into the list and printed out.

In addition, the client computer remote management method of the present invention can be implemented by a system consisting of an administrator server, an intermediate management server and a client terminal.

In other words, when information is continuously or temporarily connected in the communication between the manager server and the client terminal, a lot of load may be generated on the network, so that the intermediate management server may be set in consideration of the overload prevention and the efficiency of the manager server. Can be.

For example, when the manager server wants to send a newly created document to all client terminals, the manager server sends the document to the intermediate management server, and the intermediate management server retransmits the document to the client terminal that it manages.

In addition, since the intermediate management server and the client terminal are integrated, the administrator can change the role of the intermediate management server and the client terminal. That is, if the role of the intermediate management server can be changed to the client terminal and the client terminal to the intermediate management server, the number of management client terminals or computers can be modified.
