When archived file exceeds
limit or extraction fails
Specify how VStream Antivirus should handle files that exceed the
Maximum nesting level or the Maximum compression ratio, and files for
which scanning fails. Select one of the following:
• Pass file without scanning. Scan only the number of
levels specified, and skip the scanning of more deeply
nested archives. Furthermore, skip scanning highly
compressible files, and skip scanning archives that
cannot be extracted because they are corrupt. This is
the default.
•
Block file. Block the file.

protected file is found in

• Pass file without scanning. Accept the file without
scanning it. This is the default.
•
Block file. Block the file.

protocol anomalies, by selecting one of the following:
• Ignore and continue scanning. Log the corrupt file or
protocol anomaly, and scan the information on a best-
effort basis. This is the default.
• Block file. Block and log the corrupt file or protocol
anomaly.
