[0065] see figure 1 , the flow chart of the first embodiment of the method for processing computer viruses in this application:

[0066] Step 101: Pre-setting several virus scanning modes, which occupy different system resources when scanning files.

[0067] Among them, several virus scanning methods are arranged in descending order of system resources occupied, including at least two of the following methods: a memory scanning method for virus scanning based on the scanning results of scanned files stored in the cache, wherein the scanning results include files determined to be malicious File attribute information of files or non-malicious files, file attribute information includes file size, file modification time and file path; list scanning method for virus scanning through at least one of the pre-saved blacklist and whitelist; through antivirus engine Engine scan method for virus scan.

[0068] Step 102: Obtain the file to be scanned.

[0069] Step 103: Call the corres...

[0103] see Figure 4 , is the block diagram of the first embodiment of the device for processing computer viruses in this application:

[0104] The device includes: a setting unit 410 , an acquiring unit 420 and a scanning unit 430 .

[0105] Wherein, the setting unit 410 is used to pre-set several virus scanning modes, and the system resources occupied by the several virus scanning modes when scanning files are different;

[0106] An acquisition unit 420, configured to acquire the file to be scanned;

[0107] The scanning unit 430 is configured to call a corresponding virus scanning method to scan the file to be scanned according to the sequence in which system resources occupied by the virus scanning methods are small and arriving.

[0108] Wherein, the several virus scanning modes set in the setting unit 410 include at least a first virus scanning mode and a second virus scanning mode, and the system resource occupied by the first virus scanning mode is smaller than that ...

Abstract

The embodiment of the invention discloses a method and device for handling computer viruses. A plurality of virus scanning modes are preset; and system resources occupied by the plurality of virus scanning modes during scanning files are different. The method comprises the following steps of: acquiring files to be scanned; and calling corresponding virus scanning modes to scan the files to be scanned according to the sequence from small to large that the virus scanning modes occupy the system resources. The embodiment of the invention is applied to scanning the viruses and the corresponding virus scanning modes are called according to the sequence from small to large that the virus scanning modes occupy the system resources, so that the viruses are scanned by using the virus scanning mode occupying fewer the system resources, such as a memory scanning mode, further the amount of the files required to be scanned by the virus scanning modes occupying more system resources is reduced, the virus scanning speed of the system is improved and the system resources are saved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for processing computer viruses. Background technique [0002] A computer virus is data compiled or inserted into a computer program that destroys computer functions, which will affect the normal use of the computer and can replicate itself, usually in the form of a set of computer instructions or program codes. The antivirus engine is a set of technical mechanisms for judging whether the behavior of a specific program is a virus program (including suspicious programs). The anti-virus engine is the main part of the anti-virus software, which is a program for detecting and discovering viruses, and the virus database is a collection of features of the viruses that have been found. During the anti-virus process, the features in the virus database are used to compare all the programs or files in the machine, and the programs or files that meet these f...
