The Statistics requires that you have flash player installed (it has to be the IE version of Flash) in order to be able to display them.
If this has previously worked, try uninstalling Flash Player for IE and reinstall. This is quite fortunate as there has just been a recent flash player update. See http://forum.avast.com/index.php?topic=9671.msg695416#msg695416 the >> Updates << topic, a link has been posted for the download.
