The ARA/ARC components have been implemented with internal architecture improvements, while there are also stability improvements to the Firewall, with the claim that it will now behave better with other network applications. The Software Updater tool comes with a new installation wizard, which makes it possible to now download and install multiple updates. Avast also reveals improvements to the Browser Cleanup tool, which should improve its detection and removal of tools that attempt to block it from removing unwanted toolbars. Finally, the GrimeFighter tool has been updated to support 12 more languages and offers more control over optimization via an advanced console. Two significant bugs have been fixed with this new release: the first saw the program installer hanging when attempting to remove the program at the "Stopping service: Avast antivirus" dialog, while the second led to issues uploading to Dropbox and Flickr online services.
