Avira - Action antivirus removal tool

At one time, I have experienced problem when will intend to upgrade Avira Antivirus to a newer version, uninstall the old version that should be part of the process of installing the new version doesn't run properly. Action to uninstall through Add / Remove programs didn't work also. So, as a result of this problem, we can't uninstall antivirus and also can't install new antivirus.

Problems can't uninstall an antivirus program can be due to different reasons. To overcome this problem, it could be done manually by deleting all files and remove the registry settings of the antivirus program . Besides this way, can also be done with a more simple way  that's to use antivirus program removal tool.

A removal-tool is an utility used to detect and remove specific viruses,This is not a substitute for full antivirus protection, but a tool to assist administrators or users when dealing with an infected system
