Abstract

An embodiment of the invention discloses a method, a device and a system for scanning files and aims at solving the problem of low efficiency of file scanning. The method includes: aiming at to-be-scanned sample files, respectively calculating the probability of each to-be-scanned sample file to be identified as suspicious; sorting the to-be-scanned sample files according to the probability of the sample files to be identified as suspicious; acquiring the number of the scanned files, namely K, and extracting K to-be-scanned sample files with the high suspicious probability from the sorted to-be-scanned sample files, wherein the K is a positive integer; and scanning the K to-be-scanned sample files and identifying the suspicious sample files in the K to-be-scanned sample files. By means of the method, the device and the system for scanning the files, scanning efficiency is improved, suspicious sample files can be identified as many as possible, and accuracy of the sample file scanning is improved.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method, device and system for scanning files. Background technique [0002] Malicious program is an umbrella term for any software program intentionally created to perform unauthorized and often harmful acts. Computer viruses, backdoor programs, keyloggers, password stealers, Word and Excel macro viruses, boot sector viruses, script viruses (batch, windows shell, java, etc.), Trojan horses, crimeware, spyware and adware, etc., These are examples of what could be called malicious programs. [0003] In order to prevent malicious programs from attacking the computer, it is generally necessary to install anti-virus software on the computer to scan files in the system to identify and kill malicious programs. [0004] In order to quickly identify and kill malicious programs, and at the same time reduce the resource consumption of the client, more and more current security ...
