Beta-VDF and Beta-Engine

All Avira virus definition files (VDFs) and the Avira search engine are thoroughly tested before they are made available on the download servers. This test period does of course broaden the time span between putting new detection patterns into the VDF or new exploits into the engine and their publication.
However, there might be certain scenarios in which it is primarily important to get the most recent VDFs and engine versions as early as possible. For such cases Avira provides untested, so called Beta-VDFs and Beta-Engine versions for downloading.

Avira Fusebundle Generator

A fusebundle is a an archive containing the latest engine and VDF files together with the corresponding update control files (info.gz). Its purpose is to allow a network administrator to update the Avira security products without having an Internet connection.

The Fusebundle Generator tool allows the creating of these archives locally in an incremental way. It is no longer required to download the entire archive after each engine and signature update.
