Problems solved by technology

[0004] However, there is a problem: the first method is mainly to extract fixed features about such samples after analyzing specific samples, such as codes or data at specific positions in the infection process and decryption process, such as keys at fixed positions
This method has a large detection range, but it cannot distinguish which kind of infectious virus it is, so it cannot be repaired accordingly

Abstract

The invention discloses a virus detection method. The virus detection method comprises obtaining a program to be detected and decompiling the program to be detected; extracting instruction sequence features of the post-decompiling program to be detected; detecting viruses of the program to be detected according to the extracted instruction sequence features. The virus detection method can effectively and quickly detect inflection type viruses of specific types, is low in false positive rate, and, by means of detection of instruction sequence features, is wide in detection range compared with a traditional feature code method, thereby improving detection efficiency. The invention further discloses a virus detection device and a terminal.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a virus detection method, device and terminal. Background technique [0002] Infectious viruses are viruses that infect normal files into virus files, and polymorphism means that the results of each infection are different. When a virus utilizes a polymorphic engine, it will cause the virus code to behave differently each time it is infected. [0003] At present, there are two main methods for detecting infectious viruses: the first is a targeted method, that is, to detect a specific infectious virus; the second is a universal method, that is, it can detect many an infectious virus. [0004] However, there is a problem: the first method is mainly to extract fixed features about such samples after analyzing specific samples, such as codes or data at specific positions in the infection process and decryption process, such as keys at fixed positions. The false alarm rate...
