Hi z8000783,
The “?” means that this feature cannot be installed/uninstalled in the Avast! free or Avast! pro antivirus. As you are using the free version, you can’t install Antispam, because it is only for IS and Premier. Maybe you talk about the Mail shield plugin. Could you make a screenshot with the toolbar so we can help you. You can see how to make a screenshot here: http://www.take-a-screenshot.org/. Have a nice day!
