Computerworld posted a story that Avira products are still not supported on Windows 8 and Windows Server 2012

Once Avira gets those issues ironed out, Mustaca said the company will submit its product for reevaluation by Microsoft in the hope that it will sign off on the software as being compatible with Windows 8. Company officials expect to make that submission in the coming weeks.

"We will continue to rollout (sic) patches in the next few weeks," Mustaca said. "We hope to be able to remove very soon the popup at the beginning the installation which informs the user that we don't officially support this operating system."
