Abstract

The invention provides a method and a device for detecting files. The method and the device for detecting the files are used for solving the problem that in the prior art, defense for computer viruses obtained in a virus kill-free manner is not good in effect. The method comprises the steps of when a to-be-detected file is confirmed, judging whether the to-be-detected file is detected, if the to-be-detected file is detected, confirming a time difference between final modification time of the to-be-detected file and current time, and if the time difference is within a preset time interval, outputting a prompt message used for explaining that the to-be-detected file does not contain the viruses.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for detecting files. Background technique [0002] With the development of computer technology, computer viruses are also increasingly affecting the data security or use experience of computer users. Many computers have installed anti-virus software (or claim anti-virus software, firewall etc.) for this reason to resist computer virus. In order to prevent the virus files they write from being detected by anti-virus software, some computer virus authors usually hand over the compiled virus files to the anti-virus software for detection to see if the anti-virus software can detect the file as a virus file; The software detects that the file is a virus file (the anti-virus software will output a prompt message at this time), then the author modifies the virus file and then submits it to the anti-virus software for detection, and so on, until the anti-virus sof...
