Problems solved by technology

[0003] However, as Trojan horse virus programs and backdoor virus programs have become a flood trend at this stage, they have caused great damage to the property of network users. and other processing methods to evade the detection and killing of anti-virus software, and in the existing virus program industry chain, the source code exchange method can also be used to avoid killing and thoroughly fight against anti-virus software
Therefore, the above-mentioned unfavorable factors cause anti-virus software to constantly analyze and summarize new features of v

Example Embodiment

[0021] figure 1 It is a flow chart of the virus program scanning method according to an embodiment of the present invention. As shown in the figure, the method may include the following steps:

[0022] Step 101, acquiring file information of a file to be scanned.

[0023] Step 102, according to the file information, judge whether the file to be scanned is an executable file that only uses the standard dynamic library of the Windows operating system, if so, continue to execute the virus program scanning method described in this embodiment, otherwise obtain the next file to be scanned file, and re-execute the virus program scanning method described in this embodiment.

[0024] Since Microsoft's Windows (Windows TM ) The penetration rate of the operating system is very high. Therefore, in order to increase its own infection rate, most of the existing virus programs usually use the standard dynamic library of Microsoft's Windows operating system. If it is determined that an exec...

Abstract

The invention relates to a method and apparatus for scanning virus program, wherein, the method comprises: acquiring file information of the file to be scanned; judging whether the file to be scanned is an executable file only using a standard dynamic database of a viewfinder operating system or not, if yes, the executable file can be performed for enlightened scanning. The apparatus comprises an acquiring module, a first judging module and a scanning module. The invention can greatly reduce the numbers of the files which need to be performed for matched scanning, thereby improving the matching lookup efficiency, increasing the scanning speed and reducing the misinformation ratios greatly.

Description

technical field [0001] The invention relates to a virus program scanning method and device, belonging to computer virus program scanning technology. Background technique [0002] The heuristic scanning technology based on behavior analysis is a commonly used technology in the existing virus program scanning technology. It forms a behavior heuristic feature library by analyzing and summarizing the characteristics of most known computer Trojan horse virus programs or backdoor virus programs. , the behavior heuristic library has features and feature groups based on program behavior types, and the purpose of virus detection and killing is achieved by matching virus programs according to these features and feature groups. [0003] However, as Trojan horse virus programs and backdoor virus programs have become a flood trend at this stage, they have caused great damage to the property of network users. and other processing methods to evade the detection and killing of anti-virus s...
