Avira VDF Update

Because Avira updates its detection files silently and automatically, most of our users never need to install their own virus definition updates (VDF).

Performing an Avira manual update is only necessary under special circumstances, e.g., initiating an Avira VDF update without an internet connection.

Performing an Avira manual update

Although automatic updating is the best way to stay protected, you can update Avira antivirus manually anytime. For Windows users, the easiest way is to right-click the Avira icon in the taskbar and select Start update.

You can also use our free Avira update tool to perform an Avira manual update. This utility creates an archive (fuse bundle) containing the latest engine, the Avira VDF update files and the corresponding Avira antivirus update control files (info.gz).

The names of all viruses added to the each Avira VDF update file (IVDF) are available on the VDF History page.

Why use the Avira update
free tool?

The Avira manual update tool, also known as the Fusebundle Generator, allows you to create an entire antivirus update archive incrementally. In other words, you no longer have to download an entire archive for each engine and signature update.

Decompress avira_fusebundlegen-win32-en.zip and open the avira_fusebundlegen-win32-en folder.

RUN THE AVIRA UPDATE GENERATOR.

Double click on fusebundle.exe and wait for the fuse bundle archive (the Avira VDF update, engine and control files) to be generated. A new Install folder will also be created; this is where you can save vdf_fusebundle.zip.

Open the Avira product, click Update from the top menu and select Manual Update.

LOAD THE AVIRA UPDATE ARCHIVE (THE FUSE BUNDLE).
