This method works fine. Avast is installed with my favourite settings and also my Home Edition key. Avast is also loaded at startup, BUT the systray icon isn't visible! I only tested in VMWare, so maybe that is the problem. Anyone knows how to get the avast systray icon back? EDIT: Never mind I looked into admin.ini and found this line: ShowTrayIcon=1 which should be ShowTrayIcon=0 to make the icon visible. EDIT2: I don't know why or how, but now ShowTrayIcon=1 makes the icon visible
