Containers

On this page you can manage settings used by SpIDer Guard for scanning compound files, such as archives, mail files, packed objects and other containers (i.e. the compound files that are not related to any of the types above).

You can specify the nesting level limit for each of the file types in the corresponding field; when this limit is exceeded, SpIDer Guard will not unpack a file of such type during scanning. For example, to scan the contents of the archives that are nested in archives, specify the nesting level limit of no less than 2. To disable scanning of nested objects, specify 0 as the maximum nesting level for the corresponding type of containers.

Note that increasing the maximum nesting level slows down scanning.

The Maximum compression ratio field allows you to specify the maximum compression ratio (as a compressed/uncompressed file ratio) for objects to be scanned. If the compression ratio of an object to be scanned exceeds the specified value, this object will not be scanned.
