Abstract
A method for detecting a false positive outcome in classification of files includes, analyzing a file to determine whether or not the file is to be recognized as being malicious, analyzing a file to determine whether a digital signature certificate is present for the file, in response to recognizing the file as being malicious; comparing the digital certificate of the file with one or more digital certificates stored in a database of trusted files, in response to determining that the digital signature certificate is present for the file; and detecting a false positive outcome if the digital certificate of the file is found in the database of trusted files, when the false positive outcome is detected, excluding the file from further determination of whether the file is malicious and calculating a flexible hash value of the file.
