Embodiment Construction
[0076] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0077] In practice, for a certain order of magnitude (such as 10 5 ) above the client end, if the client end above this order of magnitude all scans files with the same characteristics (such as including file name, file size, file modification time, file content description information, content information, etc.), If this kind of file is safe, it is basically safe for other users to use files with the same characteristics. According to this characteristic, this application counts the special information of a huge number of users who take a long time to complete a complete scan and is safe, and then generates a data package (upgrade patch, etc.) to be matched based on the characteristic information. When ...

The invention provides a method and a system for rapidly scanning files and relates to the technical field of networks. The method includes the steps of obtaining a data package, wherein the data package contains secure file characteristic information which is used for determining whether files in the system are secure files or not; and scanning file characteristic information of files in the system one by one and matching the file characteristic information which is scanned currently with the secure file characteristic information in the data package which marks files as secure files; skipping antivirus scanning of the current file if the file characteristic information matches with the secure file characteristic information, and going on scanning the next file; and performing antivirus scanning for the current file if the file characteristic information does not match with the secure file characteristic information, and adding the secure file characteristic information of the file into the data package when the scanning time > or >= the time threshold and the file is secure. The method and the system can reduce the time for first scanning and timely update the data package for usage by local clients or other clients.
Description
technical field [0001] The present application relates to the field of network technology, in particular to a method and system for fast file scanning. Background technique [0002] With the popularization of computers, the client basically needs to install anti-virus software to scan the files in the computer. When the antivirus software is scanning, it needs a lot of CPU calculation and disk operation, which makes the scanning process long and affects the system speed. As for the files in the computer, many files are the same, such as Windows files, many software installation package files, help files, compressed files, etc. [0003] In the prior art, the antivirus software on the client side will scan all the files in the computer and scan various contents in the files when scanning for the first time. If the files with relatively large contents are included, the scanning time will be quite large. , resulting in a very long time for the first scan. Such as for a compre...
