FIELD: antivirus technologies.
SUBSTANCE: invention relates to systems and methods of detecting malicious files. Technical result is achieved by determining the file characteristic and behavior of the file, determining a set of parameters describing a surface placed in a probability space, based on certain file characteristics and behavior of the file, generating a file display by constructing a surface in said space based on a determined set of parameters, performing search in the malicious files family displays base based on the generated file display, means for detecting malicious files from a database for detecting malicious files corresponding to a family of malicious files found in a database of mappings.
EFFECT: technical result consists in optimizing the use of computational resources when checking a file for malware.
