A method for detecting whether a file includes malware is performed on a device. The method includes extracting information of at least two predetermined items in the file; creating a genetic map for the file by altering the extracted information into a previously set format; comparing the created genetic map with a previously stored malware genetic map to obtain a similarity between the created genetic map and the previously stored malware genetic map; and determining that the file is a malware when the similarity is higher than a reference value.
