摘要

Determine the penetration rate of a file which is the subject of applying the analysis by heuristic method based on behavior, and, in response to the penetration, to adjust the level of aggressiveness in order to use in the analysis. Aggression, when prevalence is low file, to a high level, and, in the case of a high prevalence file, to a low level, to set. Using the set aggression level, applying the analysis by heuristic method based on behavior for the file. In addition to the step of setting the aggression level, heuristic analysis, the prevalence is low file, as is likely to have a malicious, and, the prevalence is high file, things are less likely to have a malicious as it may also include the step of weighting dynamically. Based on the analysis by the heuristic method based on applied behavior, it determines whether the file contains malware. If the file is determined to contain malware, blocks of the file, it is possible to take the appropriate steps, such as deletion, isolation, and / or disinfection.
