Embodiment Construction

[0067] figure 1 The method flow of file scanning in an embodiment is shown, including the following steps:

[0068] Step S110, obtaining the file to be scanned.

[0069] In this embodiment, after the scanning engine of the virus scanning and killing software or Trojan horse scanning and killing software is turned on, the files to be scanned are obtained according to the user's operation of selecting the scanning range of files on the scanning and killing interface, and these files are used as files to be scanned. In the process of obtaining the files to be scanned, in order to make the file scanning easy to maintain during the running process, multiple files to be scanned are enumerated according to the set queue length according to the operation of the user to select the scanning range of the file to form an enumeration of a specific length. Raise the queue to wait for scanning.

[0070] Step S130, extracting attribute information of the files to be scanned from the acquire...

Abstract

The invention relates to a Trojan horse scanning method, which comprises the following steps of: obtaining files to be scanned; extracting the attribute information of the files to be scanned one by one from the obtained files to be scanned; and comparing the extracted attribute information with the stored attribute information, judging whether the attribute information of the files to be scanned is the same as the stored attribute information or not, if not, scanning the files to be scanned corresponding to the extracted attribute information. According to the Trojan horse scanning method and system, when the attribute information of the files to be scanned is different from the pre-stored attribute information, the files to be scanned are safely scanned so as to judge whether the files to be scanned is identified as a normal state or not, the files to be scanned with the attribute information same as the pre-stored attribute information is not safely scanned, and the probability that the files to be scanned with the attribute information same as the pre-stored attribute information is not amended is very high, therefore, the number of the files needing to be scanned is greatly reduced, the resource consumption is flexibly reduced, the security of the files is ensured, and the scanning speed of the files is improved.

Description

【Technical field】 [0001] The invention relates to data processing technology, in particular to a Trojan horse scanning method and system. 【Background technique】 [0002] In order to maintain system security, security scans of files are often implemented by running antivirus software to identify suspicious files that affect security. After completing a security scan, the user will conduct security scan again irregularly or periodically. [0003] Files judged to be normal in multiple security scans conducted by the user will still enter the next security scan together with other files that have changed. For example, anti-virus software runs on the computer and determines normal files through file feature recognition. and suspicious files, and the suspicious files have been processed; in the next run of the antivirus software, these normal files and files that have been added, modified, etc. in the computer will also be scanned. Each security scan is a complicated process tha...
