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.
