  • Method, apparatus and terminal for detecting a malware file
    Patent number: 10176323
    Abstract: The present application discloses a method, an apparatus and a terminal for detecting a malware file. One embodiment of the method comprises: obtaining a file to be inspected; determining an entropy vector of the file; and inspecting the entropy vector of the file using a trained inspection model to determine if the file is a malware file, wherein a file type of the file is identical to the file type corresponding to the inspection model. This embodiment extracts the entropy vector of the file and determines if the file is a malware file based on the entropy vector of the file. Therefore, the technical problems existed in the art, such as a low speed, a poor capacity and a low efficiency of detecting and destroying the malware file, are addressed and the efficiency of detecting and destroying the malware file is enhanced.
