DESCRIPTION
When you select this check box, if a virus pattern is matched, the
ZyWALL overwrites the infected portion of the file (and the rest of the
file) with zeros. The un-infected portion of the file before a virus pattern
was matched goes through unmodified.
Select this check box to set the ZyWALL to send a message alert to files'
intended user(s) using Microsoft Windows computers connected to the
to interface.
Refer to Appendix C on page 899
display the alert messages.
These are the log options:
no: Do not create a log when a packet matches a signature(s).
log: Create a log on the ZyWALL when a packet matches a signature(s).
log alert: An alert is an e-mailed log for more serious events that may
need more immediate attention. Select this option to have the ZyWALL
send an alert when a packet matches a signature(s).
Select this check box to check files against the white list.
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.
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.
