FIELD: antivirus technologies.
SUBSTANCE: system for detecting a malicious file comprises: a data collection apparatus for generating, based on collected data on file execution behavior, a feature vector, characterizing said behavior, wherein the feature vector is a convolution of the collected data, formed as a collection of numbers; parameter calculation device, intended to be calculated based on a feature vector generated by the data collection means using a trained model of severity parameters calculation; analysis means designed to make a decision on detection of a malicious file, when collected data on file execution behavior satisfy a predetermined criterion for determining maliciousness, formed on the basis of the severity and limit safety degree calculated by the parameters calculation tool.
EFFECT: technical result of present invention is to increase the quality of file verification for malware.
