Manually update the anti-malware database on engines

If you want the engine to have an up-to-date anti-malware database before you upgrade the engine, you can manually update the anti-malware database on an NGFW Engine or individual nodes of an NGFW Engine Cluster.

The update command in the Management Client uses the default anti-malware database mirror URL.

You must update the anti-malware database by running the avdbfetch script on the engine command line in the following cases:

  • To use an alternative mirror
  • To use an HTTP proxy
  • To update the anti-malware database by copying the database to the engine from a USB memory stick

  2. Browse to Engines, then expand the nodes of the engine for which you want to update the anti-malware database.
  3. Right-click an engine node, then select Commands > Update Anti-Malware Database.


The anti-malware database update begins. The update can take a while.
