DESCRIPTION
When you select this check box, if a virus pattern is matched, the NXC
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 NXC 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 617
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 NXC 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
NXC 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 check files against the black list.
Select this check box to have the NXC scan a ZIP file (the file does not
have to have a "zip" or "rar" file extension). The NXC first
decompresses the ZIP file and then scans the contents for viruses.
Note: The NXC decompresses a ZIP file once. The NXC does
NOT decompress any ZIP file(s) within a ZIP file.
Note: When you select this option, the NXC deletes ZIP files that
use password encryption.
Select this check box to have the NXC delete any ZIP files that it is
not able to unzip. The NXC 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 NXC can concurrently unzip.
Note: The NXC's firmware package cannot go through the NXC
with this option enabled. The NXC classifies the firmware
package as not being able to be decompressed and
deletes it.
You can upload the firmware package to the NXC with the option
enabled, so you only need to clear this option while you download
the firmware package.
