Updated from Avast! 2280 to 2288 from within the GUI and had no issues.
Like the new animated amoeba for the tray icon as well as the more subdued interface color scheme.
but...
first off please don't replace my more up to date (12.0.199) Avast! Internet Security Google Chrome browser add-on with the BETA version of the same add-on (12.0.197). Bit annoying having to remove the BETA version and reinstalling the version I already had from the Chrome Web Store.
Second while I like the more customizable nature of this new "Game Mode", I'd like to remind the Avast! team that they're, at least in my eyes, an Antivirus and not some tool to magically make my system run better. Having the options of messing with my power plan, process affinity, windows updates, and windows notifications automatically set to enabled was extremely annoying. But, thanks to this new interface, is at least very easy to manage.
Also the context menu icon for scans is still the older Avast! yellow. Not sure if that has been missed but thought I would point that out.
Keep up the good work. =D
