After the two minute period, it simply asks that I need to elevate but there are no buttons to click or anything, then that dialog box disappears and nothing happens afterwards. There are no further prompts. During the two minute countdown, the dialog box has the buttons "finish" and "cancel". Do I need to click finish? That's the only thing there is for me to actually interact with.
Also to add to the list of symptoms, it seems that certain services are not starting up consistently/correctly. Avast sometimes completely doesn't start, or it starts but is disabled, or it starts but is only partially enabled. Sometimes MBAM starts, sometimes it doesn't. Sometimes the sound starts disabled until I set a volume, this time, I don't even see the volume icon on the tray.
