If you uninstalled Avira via Add/Remove Programs only, you might still want to run Avira's uninstall tool to be sure it has 100% uninstalled all tidbits scattered on your drive and in the registry to avoid possible future issues. Here's a link to the uninstall tool download site:http://www.avira.com/en/support/av7_upgrade_tools.html
After running the uninstall tool, Avast probably would have installed OK for you. I run Avast and it sure is quick to notice those remnants of previous antivirus programs during installation. It just thought you might have two AV's on your system------a definite no-no.
The AVG, if you're happy with it, could yet encounter problems if there are bits of Avira still in your registry or lurking elsewhere on your pc. I'd definitely run that Avira uninstall tool just to be sure. You might even want to do a search on keyword AVIRA and see if you have any files/folders Avira left, too, and delete them.
