Abstract
A virus detection method, a terminal, and a server are provided. The method includes performing preprocessing on an obtained to-be-processed file according to a preset policy, to obtain a part that is in the to-be-processed file and whose stability is greater than a first threshold as effective information. The effective information is calculated to obtain a first characteristic parameter value. The first characteristic parameter value is transmitted to a server for performing detection by means of virus comparison, and a detection result of the virus comparison is received. Virus scanning is performed on a local file according to the detection result.
