(ZIP and RAR)
Select this check box to have the ZyWALL scan a ZIP file (the file does not have to
have a “zip” or “rar” file extension). The ZyWALL first decompresses the ZIP file
and then scans the contents for viruses.
Note: The ZyWALL decompresses a ZIP file once. The ZyWALL
does NOT decompress any ZIP file(s) within a ZIP file.

files that could
not be
decompressed
Note: When you select this option, the ZyWALL deletes ZIP files
that use password encryption.
Select this check box to have the ZyWALL delete any ZIP files that it is not able
to unzip. The ZyWALL cannot unzip password protected ZIP files or a ZIP file
within another ZIP file. There are also limits to the number of ZIP files that the
ZyWALL can concurrently unzip.
Note: The ZyWALL’s firmware package cannot go through the
ZyWALL with this option enabled. The ZyWALL classifies
the firmware package as not being able to be
decompressed and deletes it.
You can upload the firmware package to the ZyWALL with the option enabled,
so you only need to clear this option while you download the firmware package.
