Time to do some serious updates. Im going to install service pack 3. But first of all I want to do a complete uninstall of Online Armor 18.104.22.168 paid and Avira Antivir Free. When serv.pack 3 is installed I want to do a fresh install of OA and Avira latest versions. How can I make sure I do a complete uninstall of OA and Avira? Anything I should know before installing serv.pack 3?
