Embodiment Construction

[0039] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] figure 1 It is a schematic flow chart of the first embodiment of the virus detection method of the present invention; figure 1 As shown, the virus detection method of the present invention comprises the following steps:

[0041] Step S01, identifying the file type of the file to be detected;

[0042] When the system receives the file to be detected sent by the user, or the system captures the corresponding data for virus detection, the system identifies the file type of the file to be detected; for example, identifies whether the file to be detected is an exe file or a pdf file and other file types.

[0043] Step S02. According to the file type, call the vi...

Abstract

The invention discloses a virus detection method and device. The virus detection method includes the steps of identifying a file type of a file to be detected; calling a virtual machine system mirror image file corresponding to the file type and / or an application program copyright incremental snapshot corresponding to the file to be detected; loading the virtual machine system mirror image file and / or the incremental snapshot by means of virtual machine software to generate a virtual machine instance, and operating the file to be detected on the virtual machine instance; detecting the operation state of the virtual machine instance, and analyzing whether the file to be detected includes viruses. The virus detection method and device have the advantage of being capable of carrying out virus detection on multiple copyright application programs on the same virtual machine system mirror image file.

Description

technical field [0001] The present invention relates to the field of computers, and also to virtualization technology, in particular to a virus detection method and device. Background technique [0002] With the continuous development of computer technology, viruses are no longer limited to executable files in the form of exe. In html (Hypertext Markup Language, Hypertext Markup Language), pdf (Portable Document Format, Portable Document Format), swf (Shock wave Flash, the file format of animation design software) and other formats may exist. Because the virus format is complex and has certain dynamic characteristics, the virus detection method gradually shifts from the traditional signature technology to the virtual execution technology. [0003] Because the triggering of viruses depends on specific software versions, for example, some viruses can only act on Internet Explorer6 browsers or specific Adobe Reader (pdf reader) versions. After patching or updating the version ...
