Embodiment Construction

[0027] In order to improve the efficiency of virus detection and killing of video files, the embodiment of the present invention provides a method for virus detection and killing of video files. In this method, the video file is analyzed to find the virus-infected video data segment, and then the infected video data segment is found. Virus video data segment undergoes virus removal processing.

[0028] The method for virus checking and killing a video file provided by the embodiment of the present invention, as shown in FIG. 4, specifically includes:

[0029] Step 401: Read the video data segment of the video file;

[0030] The file structure of the video file is shown in Figure 5. The video file contains two parts, a description data segment (Tagged Chunk) and a video data segment (Subchunk). The data describing the data segment is used to describe file information, such as file size information and sampling rate information. Etc.; the data of the video data segment is video data...

Abstract

The inventive embodiment discloses a virus checking and killing method for video files. The method includes that: video data sections of a video file is read out; when the data format of the video data section is different from that of the video file, the video data section is determined as a virus-infected video data section, and is processed by virus elimination. The inventive embodiment also discloses a virus checking and killing apparatus. The invention can greatly enhance the efficiency of virus checking and killing of the video files and saves system resources.

Description

Technical field [0001] The invention relates to the field of virus checking and killing, in particular to a method and equipment for virus checking and killing video files. Background technique [0002] Currently, there are two main ways to implement virus detection on files: [0003] The first is to check and kill viruses based on the virus database. [0004] As shown in Figure 1, the virus detection and killing based on the virus database is to use the existing virus feature database. The scanning module will match the features of the file to be scanned with the virus information in the virus feature database. If the match is found, the file contains a virus that is compatible with the virus. Characteristic data, the file is considered to be infected by a virus, and the removal module can be notified to remove the file. [0005] Common viruses change the program flow by modifying some key data structures in the executable file (PE), so that the virus can be executed during norm...
