Abstract

The invention provides a virus detection method and a virus detection device. The virus detection method comprises the following steps: acquiring the header information and the suffix information of a to-be-detected file; according to the header information or the suffix information, acquiring each compressed package contained in the file, and uncompressing each compressed package to acquire an uncompressed file; performing virus scanning on the uncompressed file. According to the method, virus detection can be performed on the compressed packages, and the virus detection effect is enhanced.

Description

technical field [0001] The invention relates to the field of anti-virus technology, in particular to a virus detection method and device. Background technique [0002] With the development of anti-virus software and the increase of transmission channels, virus authors are also trying their best to make the virus evade the detection of anti-virus software during the transmission process. Among them, the method often used by virus authors is compression, which spreads virus files by compressing them into a format that antivirus software cannot decompress but common decompression software can decompress. [0003] At present, most anti-virus software will not perform special processing on the compressed package for the sake of efficiency. When the user performs virus detection on the compressed package, it usually needs to decompress the compressed package first, and then scan the decompressed file for viruses. However, this method needs to be decompressed by decompression soft...
