Are you in need of uninstalling Avira Antivir? Several days ago, one of my friends brought her laptop and asked me to help her remove Avira Antiviru. She said she uninstalled it through Control Panel Add/ Remove Programs but an error message popped up and stopped its uninstalling. Luckily, it only took me no more than 10 minutes to completely remove Avira. If you have the same problem and don't know what to do, follow my steps below.
