Automatic manual updates in AVG free

Hi!

I'm thinking on ditching NAV for AVG's free edition. I have a couple of computers so in NAV I would just download the latest definitions file into one computer and let the others run it remotely (using their start up script).

How do I accomplish the same thing with AVG, which definitions come as BIN and not as a stand alone EXE?

How can I make it realize the latest BIN file sits in, say, c:\foo.bin, without launching AVG manually and clicking "update" + "ask for location" (like AVG's forum says)?

Thanks!

 

One more attempt...
