Manual antivirus database updates
Use the following procedure to update your antivirus database manually. This procedure restarts the DFL-500.
If you have configured automatic virus database updates, you can also manually update your antivirus database by
going to Anti-Virus > Config > Update and clicking Update Now.
• Download the latest antivirus database from the D-Link support website at http://tsd.dlink.com.tw and
copy it to the computer that you use to connect to the DFL-500 web-based manager.
• Start the DFL-500 web-based manager and go to System > Status .
• To the right of the Antivirus Database Version click Antivirus Database Update .
• Enter the path and filename for the antivirus database file, or click Browse and locate the file.
• Click OK to upload the antivirus database to the DFL-500.
The DFL-500 uploads the antivirus database and restarts. This takes about 1 minute.
• Go to System > Status to confirm that the Antivirus Database Version information has been updated.
When a new virus protection database is made available by D-Link, you should upgrade your DFL-500 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 See High level virus protection for your internal network to 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.
Automatic antivirus database updates
You can configure the DFL-500 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-500 automatically downloads and installs the
updated database.
You can specify the IP addresses of two update centers and configure the DFL-500 to check and download
updated databases once a day, once a week, or once a month.
The DFL-500 writes a message to the event log when it checks for antivirus updates. When The DFL-500
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.
• Specify whether to check for and download updates:
Daily
Once a day.
Weekly
Once a week.
Monthly
Once a month.
• Click Apply to save your changes.
The next antivirus database update takes place in one day, week, or month from the time at which you
saved your changes.
