File virus searching and killing method and device, electronic equipment and storage medium

Abstract

The invention discloses a file virus searching and killing method and device, electronic equipment and a readable storage medium, and the method comprises the steps: obtaining a to-be-detected file, and judging whether the to-be-detected file is a file resumed by using a breakpoint; if the to-be-detected file is the file resumed by using the breakpoint, acquiring a download link of the to-be-detected file; obtaining a complete file corresponding to the to-be-detected file based on the downloading link; and obtaining a target searching and killing result obtained by performing virus searching and killing on the complete file. When the to-be-detected file needs to be subjected to virus searching and killing, whether the to-be-detected file is subjected to breakpoint resume or not is firstly judged; if so, the current to-be-detected file is a partial file is presented, and the complete file corresponding to the to-be-detected file is acquired instead of directly virus searching and killing are performed on the file so as to perform virus searching and killing on the complete file to obtain the target searching and killing result, so that the false alarm rate caused by performing virus searching and killing on the partial file in a breakpoint resume scene can be avoided; and the virus searching and killing accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer technology, and more specifically, to a file virus scanning and killing method and device, an electronic device, and a computer-readable storage medium. Background technique [0002] Resumable uploading of client software means that when downloading or uploading, the downloading or uploading task, such as a file or a compressed package, is artificially divided into several parts, and each part uses a thread for uploading or downloading. In case of network failure, you can continue to upload and download the unfinished part from the part that has already been uploaded or downloaded, and there is no need to start uploading and downloading from the beginning, which can save user time and improve work efficiency. [0003] However, virus killing needs to rely on the entire file. In the application scenario of multi-thread or resumable upload, each thread only downloads part of the file content for up...

[0003] However, virus killing needs to rely on the entire file

In the application scenario of multi-thread or resumable upload, each thread only downloads part of the file content for uploading or downloading. If it is sent to the antivirus engine for scanning and killing, the incomplete file will be regarded as a threat to the antivirus engine. Unknown threat samples lead to inaccurate recognition by the antivirus engine, resulting in a high false positive rate
