File 
decompression

Enable file 
decompression 
(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. 

Destroy 
compressed 
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.
