File Scanning Methods, Client Devices, and Servers

Abstract

The invention discloses a file scan method, a client device and a server, and belongs to the field of computer defense. The method comprises the following steps: the client device receives instructions of carrying out assigned scanning; the client device sends a query request to the client device, and the query request carries scan characteristic values of the client device, so that the server returns query results according to the scan characteristic values of the client device, wherein the scan characteristic values comprise characteristic values of scan items and characteristic values of restoration logic; and the client device carries out the assigned scanning according to the query results returned by the server. According to the invention, before the assigned scanning by the client device begins, the query through the server needs to be carried out every time to know whether the present scan item and the restoration logic change, and according to the returned query results, the assigned scanning is carried out; and compared with file scan methods, client devices and servers in the prior art, through interaction with the server, the real-time degree of the assigned scanning and the efficiency of virus defense are improved.

Description

technical field [0001] The invention relates to the field of computer defense, in particular to a file scanning method, a client device and a server. Background technique [0002] With the development of computer technology, in order to prevent virus infection, the current client devices generally use local scan items and repair logic to scan and kill viruses and Trojan horses. The scan and its corresponding repair logic are written when the anti-virus version is released. Therefore, the client device can effectively deal with some existing risks during scanning. [0003] Since the scan items and repair logic for viruses are localized on the client device and are also fixed on the client device, this will lead to some limitations. After the existing scan items and repair strategies of the client device are identified, New viruses or risks can easily bypass the detection and killing of client devices, and since the release of new versions for client devices requires a certai...

Problems solved by technology

[0003] Since the scan items and repair logic for viruses are localized on the client device and are also fixed on the client device, this will lead to some limitations. After the existing scan items and repair strategies of the client device are identified, New viruses or risks can easily bypass the detection and killing of client devices, and since the release of new versions for client devices requires a certain period of time, there is a risk of client devices being infected during this period. Virus defense low efficiency and poor real-time performance
