I've been using Mamutu for many months, and it co-exists peacefully with Avira Antivir Free and Malwarebytes. When installing any new software download I have to disable Mamutu until the installation is complete on Vista 32-bit, but that's not a problem. Unfortunately, that step of disabling Mamutu doesn't work for the new Avira Antivir 2012 Edition. The Avira installer wants me to uninstall Mamutu before it installs the new version of Avira Antivir. Now what do I do?
