Some extracted files may be missing in the report since the maximum number of extracted files was reached during the analysis. You can increase the limit in the configuration settings.

The maximum number of reputation file hash requests (20 per analysis) was exceeded. As a result, the reputation status could not be queried for all file hashes. In order to get the reputation status for all file hashes, please increase the 'Max File Hash Requests' setting in the system configurations.
