Abstract

The embodiment of the invention discloses a Loader virus searching and killing method. The method comprises the first step of obtaining a dynamic link library (DLL) file of a target detection program, the second step of extracting multiple derived functions of the DLL file of the target detection program, the third step of judging whether one, and only one derived function which has a logical function exists among the multiple derived functions of the DLL file or not, and if yes, determining the DLL file of the target detection program is a Loader virus, and the fourth step of removing or isolating the target detection program. Correspondingly, the embodiment of the invention further discloses a Loader virus searching and killing device and a terminal. The Loader virus searching and killing method and device and the terminal can achieve searching and killing of the Loader virus and have the advantages that the maintenance cost is low and accuracy is high.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method, device and terminal for checking and killing Loader viruses. Background technique [0002] Trojan horse virus is a common computer virus, which hides in the host computer. Virus authors can use Trojan horse virus to destroy the host computer, steal files, or remotely control it. For example, virus authors can use Trojan horse virus to remotely control the host computer to execute Sensitive operations such as "switching the camera" or "switching the microphone" pose a great threat to the user's privacy. Wherein, loader (Loader) virus just belongs to trojan horse virus, and loader virus usually pretends to be the DLL (Dynamic Link Library, Dynamic Link Library) file of the main program, and runs with the main program startup. It should be pointed out that the main program attached to the loader virus is often a program of a well-known company, with a digital sig...
