Interesting - well Avast uses the Sciterengine to develop it's GUI (therefore it uses HTML/CSS for the GUI using the engine) so it probably just messed up somewhere for the text value (most likely reads it from a language file on disk) and the CSS positioning.
Since I mentioned that: ESET, Comodo, Bitdefender and Norton all use Sciter also. Avast has been using Sciter for awhile, and before this they used htmlayouts for a very long time (also by the makers of Sciter, now unsupported and development ended).
New GUI is great. It's refreshing. All these years it has been almost the same. At least in its early days it could change to a car radio...it was interesting at some point
