Updating your antivirus database
The antivirus database contains the information the virus scanning engine uses to scan files for viruses
and worms. This database is continuously updated by D-Link as new viruses and worms are encountered
and defined.
You should keep your antivirus database up to date so that the DFL-1000 can protect your network from
new viruses. You can update your antivirus database manually, or you can configure the DFL-1000 to
update the antivirus database automatically.

When a new virus protection database is made available by D-Link, you should upgrade your DFL-1000 as
soon as possible. If a new virus is reported and you are not able to upgrade the anti-virus database
immediately, you can use the procedure
provide temporary added protection. Because this procedure results in the blocking of all files that might be
dangerous, whether they are infected or not, there may be some inconvenience to users.
Configuring automatic antivirus database updates
You can configure the DFL-1000 to automatically check an update center to see if a new version of the
antivirus database is available. If it finds a new version the DFL-1000 automatically downloads and
installs the updated database.
You can specify the IP addresses of two update centers and configure the DFL-1000 to check and
download updated databases once a day, once a week, or once a month.
The DFL-1000 writes a message to the event log when it checks for antivirus updates. When The DFL-
1000 downloads a new version of the antivirus database it also records an event log message and sends
an Alert email.
To configure antivirus updates:
•
Go to Anti-Virus > Config > Update .
•
Enter the IP address or domain name of one or two antivirus database update centers.
•
Click to select Periodic Update to turn on the automatic antivirus database updates.
