I have the latest Avast Free version installed and it has the Mail
Shield activated.  Normally I disable the Mail Shield, but when doing
so it makes the System Tray icon complain about not being fully
protected.  The problem is the program is appending an Avast signature
at the end of my outgoing mail and I don't want that.  I haven't found
a way to turn it off though.

Does anyone know how to either disable the Mail Shield without dire
warnings or disable the Avast signature line?
