Avast! Antivirus does not work anymore. It expired and I can't remove it or install it anymore. What can I do?
You can use the uninstall utility to get rid of the application. It's a custom tool designed to remove all the versions of avast! from your computer. However, if you don't want a pro version, there is always the possibility to use the application freely. You can download a new version from its official website after you have run the installer.
