Hi Dave, it works if the GUI is already open. Seems to be a dependency.
Of course it does, that is what we are saying, but it doesn't if you go directly to the virus chest from the tray icon. You have to ask why Avast would change the dependency.
This is the same as the decision to open the UI when using the context menu 'Quick' scan another monumental pain in the backside. The tray icon context menu is meant to make access quicker to elements that are buried in the UI. Avast have promised/talked about improving the context menu of the tray icon, but nada, zilch, sod all, if anything it is more depreciated.
