The present disclosure discloses an information processing method, including the steps of acquiring at least one executable file of a specified type; extracting a first operation instruction from the at least one executable file of the specified type; determining the first operation instruction as a feature instruction if a preset policy is met; extracting a feature value of the feature instruction; constructing a virus classification model based on the feature value of the feature instruction for obtaining a virus structural feature parameter; extracting a second operation instruction from at least one to-be-analyzed file when the at least one to-be-analyzed file is identified according to the virus classification model; and identifying the to-be-analyzed file as a virus file if the feature value of the second operation instruction corresponds to the virus structural feature parameter.
