Signature Updates
Regular updating of signature files lets you keep your system safe by
enabling your system to identify the newest viruses. There are two ways to
update signatures:
Update automatically from a local HTTP server at the scheduled time.
Update manually by uploading signature files.
To automatically update the signature from the local HTTP server:
Before using the HTTP server for signature updating, you need to:
1. Go to the McAfee DAT upgrade website:
http://update.nai.com/Products/CommonUpdater/.
2. Download the oem.ini file.
3. Download the DAT file. Its filename (usually is avvdat-xxxx.zip) corresponds to the
name shown after =FileName text in the oem.ini file.
4. Upload the two files to the local HTTP server
5. Make sure the files are accessible from the URL in the format of
http://hostname/oem.ini and http://hostname/avvdat-xxxx.zip.
Regularly check the MaAfee DAT upgrade website to ensure signature files on your
local site are up-to-date.
Click System Config> Antivirus in the menu bar at the top of the page.
In the Signature Updates area, select the Update automatically from a
local mirror option.
Enter the URL of the site and related username and password. The URL
should start with http://, for example, http://update.com
Click Schedule and choose one of the following options in the dialog
box that appears:
― Daily: Update will be performed on the specified day and time each
week. You can select multiple days.
― Monthly: Update will be performed on the specified day and time
each month.
Click Update to apply settings.
To manually update the signature:
Click System Config> Antivirus in the menu bar at the top of the page.
In the Signature Updates area, click Upload signature update file.
Specify the update file, and then click Upload.
