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.

If this is a black list entry, select this option to have the ZyWALL apply
this entry when using the black list.
If this is a white list entry, select this option to have the ZyWALL apply
this entry when using the white list.
File Pattern
For a black list entry, specify a pattern to identify the names of files that
the ZyWALL should log and delete.
For a white list entry, specify a pattern to identify the names of files that
the ZyWALL should not scan for viruses.
Use up to 80 characters. Alphanumeric characters, underscores (
_
),
dashes (-), question marks (?) and asterisks (*) are allowed.
A question mark (?) lets a single character in the file name vary. For
example, use “a?.zip” (without the quotation marks) to specify
aa.zip, ab.zip and so on.
Wildcards (*) let multiple files match the pattern. For example, use
“*a.zip” (without the quotation marks) to specify any file that ends
with “a.zip”. A file named “testa.zip would match. There could be any
number (of any type) of characters in front of the “a.zip” at the end
and the file name would still match. A file named “test.zipa” for
example would not match.
A * in the middle of a pattern has the ZyWALL check the beginning
and end of the file name and ignore the middle. For example, with
“abc*.zip”, any file starting with “abc” and ending in “.zip” matches,
no matter how many characters are in between.
The whole file name has to match if you do not use a question mark
or asterisk.
If you do not use a wildcard, the ZyWALL checks up to the first 80
characters of a file name.
