Problems solved by technology

[0005] In the prior art, once a new virus or virus variant appears, it is necessary for an anti-virus engineer to manually or semi-manually extract the signature code of the virus, and then update the virus signature library of the anti-virus software on the user's computer by upgrading, for this purpose. The process is completed manually or semi-manually, so it will consume a lot of manpower, material resources, especially time, and the extraction efficiency of virus signatures is low

Abstract

The embodiment of the invention discloses a method and a device for extracting a virus feature code. The method comprises the steps: classifying a virus sample; and extracting a feature code of the virus sample according to a classified result of the virus sample. In the embodiment of the invention, the virus feature code is extracted through classifying a virus document according to the classified result, and the extraction efficiency of the virus feature code is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a method and device for extracting virus signatures. Background technique [0002] The rapid development of computer network technology, especially the application of the Internet has become more and more extensive, which has brought unprecedented mass information and made the spread of computer viruses more convenient. After the emergence of computer virus generation tools, the security of network information has been greatly threatened. Once these malicious programs are launched, they will cause damage to the computer system, such as tampering with files, affecting system stability and execution efficiency, stealing information, and causing system paralysis or even destroying system hardware, seriously threatening information security. [0003] At present, most antivirus software technologies commonly used can only detect and kill known types of malicious programs, and ...
