Windows 8.1 Compatibility Information

All Avira workstation products in version 2014 are Windows 8.1. certified.
The Avira products in version 2013 are not Windows 8.1. certified, but, with the exception of Internet Security and Professional Security, all are fully functional. The same applies to Windows 8.0.

Avira Free Antivirus 2013 and Avira Antivirus Premium 2013 will be updated automatically to version 2014.
Avira Internet Security 2013 and Avira Professional Security 2013 will not be certified, because they use legacy technologies for which Microsoft does not give a "Compatible with" certification anymore.

Since November 12th, 2013 you can transform your Avira Internet Security license into a license for Avira Internet Security Suite without any additional cost. Avira Internet Security Suite 2014 is completely compatbile with Windows 8.1. If you are still using Avira Internet Security 2013 we recommend to update your product immediately.
