Beta-Version [6.0.1352]
This is technically identical to the previous beta build (6.0.1351) but the updater is now fixed. This means two things: a) you can update use the 6.0.1352 installer to do an update from any previous build (without losing your settings), and b) you will stay on the beta stream and so won't be offered "downgrade" to the previous official build (1289) anymore.
The UI of the new version also includes the avast! Market, a new way to get info (and potentially try/buy) other avast products. This section can be hidden by disabling the avast! recommendation features in the avast! Community settings.
Also, the new stuff is available only in English -- no need to report "localization problems" in this case.
