Problems solved by technology

If the delay reporting scheme is adopted, the malicious files are released first, and then the malicious files are security detected, it may take at least 1 or 2 seconds in the middle, but this 1 or 2 seconds is enough for the malicious files to block nearby terminals. are infected, and so on, as long as there is a delay, there will be uncontrollable situations

Abstract

The invention discloses a file security checking and killing method, device and system, and relates to the information security technology. The file security checking and killing method, device and system mainly aim at effectively checking and killing rapidly-diffused vicious files. According to the main technical scheme, the method comprises the steps that a cloud server obtains a to-be-detected file uploaded by clients; security detection is carried out on the file; when it is detected that the file is a vicious file, file features of the vicious file are obtained, the detection result is returned back to the clients, and the file features are sent to all the clients within the preset range so that the clients receiving the file features can locally complete checking and killing of the vicious file. The clients receive the file features of the vicious file sent by the cloud server, the clients are located within the preset range, and the vicious file is locally checked and killed for the first time according to the file features. The file security checking and killing method, device and system are mainly used for the real-time file checking and killing process.

Description

technical field [0001] The invention relates to an information security technology, in particular to a method, device and system for checking and killing files. Background technique [0002] Real-time scanning for file security is different from scanning for file threats. For file threat scanning, after the file is scanned, the client can perform security processing on the file according to the file scanning result. This method of real-time scanning and killing of files is not feasible. For example, when a user needs to open a file, if the file is blocked and waits to detect whether there is a threat, and then allow it to open or block it, it will take a long time time, resulting in a very poor user experience. Therefore, in order to ensure the timeliness of file opening, at present, the method of delayed reporting is generally used to detect and kill the file in real time, that is, the file is allowed to be opened first, and then the file is uploaded to the cloud for threa...
