Abstract

The embodiment of the invention provides a file scanning method and device. According to the method provided by the embodiment of the invention, a file to be scanned is obtained, and further, the file is identified according to at least one item from the file size and the file feature data, so that identification results are obtained; the identification results include the result that the file is a trusted file, the result that the file is an untrusted file or the result that the file is an unknown file, so the unknown file can be subjected to virus scanning processing according to the identification results. Only the unknown file needs to be subjected to virus scanning processing, but not all files need to be subjected to the virus scanning processing, so the problem that more system resources of a terminal are occupied due to the virus scanning processing on each file in the prior art can be avoided, and the processing performance of the terminal is improved.

Description

【Technical field】 [0001] The invention relates to computer technology, in particular to a scanning method and device for documents. 【Background technique】 [0002] A virus is data compiled or inserted into an application program that destroys terminal functions, which will affect the normal use of the application program and can replicate itself, usually in the form of a set of instructions or program codes. Viruses are destructive, replicative and infectious. The terminal can use the antivirus engine to perform virus scanning processing on files stored in the terminal, so that even if a virus file is found, corresponding defense processing is performed. [0003] However, due to the large number of files stored in the terminal, performing a virus scanning process on each file will occupy more system resources of the terminal, thereby reducing the processing performance of the terminal. 【Content of invention】 [0004] Aspects of the present invention provide a file scanni...
