Abstract

The invention discloses a scanning method and a scanning system for file samples. The scanning method includes that as for grey file samples in the file samples, to-be-scanned grey file samples are selected from stored grey file samples according to a preset strategy; one assessor for scanning the grey file samples is selected according to updating records of each assessor and / or scanning records of each assessor; the selected assessor is used for scanning the to-be-scanned grey file samples and storing scanning results, so that the scanning results are returned after a request inquiring whether file samples are safe or not is received; and the grey file samples are file samples with unknown safety. Resources of scanning devices are saved, scanning efficiency is improved, and scanning speed is increased.

Description

technical field [0001] The invention relates to the field of computer network security, in particular to a method and system for scanning file samples. Background technique [0002] In the field of network security, it is usually necessary to scan and kill virus files. Virus file is an umbrella term for any application file that is intentionally created to perform unauthorized and often harmful actions. For example, including: computer viruses, backdoor programs, keyloggers, password stealers, Word and Excel macro viruses, boot sector viruses, script viruses, Trojan horses, etc. [0003] In the prior art, the method adopted for scanning and killing virus files mainly depends on the signature database mode. The signature library is composed of signature codes of virus file samples collected by the manufacturer, and the signature code is the difference between the virus file and the legitimate file that the analysis engineer finds, and intercepts a piece of file code similar...
