Abstract

An embodiment of the invention discloses a virus detection method and a virus detection engine. The virus detection method and the virus detection engine are applied to the field of virus detection and can solve the problem that existing virus detection is high in time consumption and low in efficiency. The method includes the steps that application files are received, wherein the application files comprise certificate files; certificate signatures are extracted from the certificate files of the application files, the certificate signatures correspond to the certificate files one to one, the certificate signatures are matched with a signature database, and whether the application files are viruses or not is judged according to matching results. The virus detection method and the virus detection engine are applied to virus detection.

Description

technical field [0001] The invention relates to the field of virus detection, in particular to a virus detection method and a virus detection engine. Background technique [0002] Signature code is a kind of characteristic information, which is usually a continuous character string without spaces extracted from a virus code, and is stored in the virus database as a characteristic record of this type of virus. In the early days of virus development, signature technology played a huge role in fighting viruses, and it is still the most basic supporting technology for the entire anti-virus system today. But now the deformation technology has been widely adopted by viruses, and it is almost impossible to detect viruses without signature codes in the virus database. [0003] Existing virus detection engines usually perform matching detection based on the feature information of certain viruses. Matching detection needs to analyze the application executable file, and the size of th...
