See the following: http://www.browserdefender.com/file/686084/site/free-av.com/ It discusses the installation of Avira AV. Near the bottom of the page it mentions Registry changes where it says your empty Empty Registry Key was created. Maybe they can't be deleted with Avira running, and would probably be re-created if you turned off Avira and deleted them. If they were repaired with Avira off that might solve your problem.
