We are always improving our detection capabilities, including the update mechanism.
In the last couple of years, we switched to a modular approach that allows us to release smaller files instead of huge ones. The existing nVDF (vbase000.vdf - vbase031.vdf) was replaced by xVDF (xbv00000.vdf - xbv00255.vdf), our current format for updating virus patterns.
The xVDF format brings two great benefits:
- The first is that the xVDF files only contain incremental updates and never download duplicate data. For you, this means smaller downloads, quicker updates, and less bandwidth consumption.
- The second benefit is that all the incremental updates are compiled into one file that is loaded by the engine, making the Avira application load quicker, which in turn improves the performance of your system.
Commencing 2018-03-26 we moved ahead and exclusively started providing xVDF pattern updates. We then discontinued nVDF pattern updates for older products such as AV13 and earlier.
This ensures Avira customers enjoy the latest in detection technology and will make the Avira portfolio future-proof.
