You seem to be having a few problems with ShadowUser like entering your registration key in a sandbox environment only to it isn’t saved in the real environment, so when you start avast again under ShadowUser you are asked for the key again. Did you ever resolve that, there is no resolution information o the topic, http://forum.avast.com/index.php?topic=26108.0.
It seems you are having the same issues with updates in a virtual environment not being saved in the real environment.
