Come and see the new AV9!

The new version 9 provides new and enhanced features for Avira AntiVir Windows desktop products and for Avira AntiVir Windows Server. In most cases you don't need to do anything to migrate to AV9 - just a few mouse-clicks.

Everything you need to know for migration

What does migration mean?
Unlike an update, where the program version is updated without requiring an installation, migration or upgrade means that a previously installed version of the program needs to be uninstalled before the new version can be installed.

Which products are affected by the migration?
The following Avira AntiVir products for Windows: Avira AntiVir Personal, Avira AntiVir Premium, Avira Premium Security Suite, Avira AntiVir Professional and Avira AntiVir Server (Windows) are affected by the migration. Migration to version 9 is necessary if you have one of these products.

Why do you have to migrate?
Migration is required when the basic structure of the program has changed to such an extent that they are no longer consistent with the structures of the prior version and it is not possible to take over these old structures to the new version.

Preparing the migration
You don’t need to migrate immediately to version 9! Avira will support version 8 of the affected products until 31 March 2010. Up to then Avira will continue to provide updates of the engine, the detection sample database and the program. You can decide when to migrate within this period of 12 months.

Different migration or upgrade scenarios
Avira AntiVir desktop products for Windows are used for a variety of scenarios: for single workstation and multiple-workstation scenarios or for centrally administered implementations. In all scenarios migration can be performed nearly automatically, but there are differences in the migration process.
