What do I do?  This keeps popping up!!

Avast: Unable to connect to the Avast engine.
Avast mail protection cannot be started.

The add-in "C\Program Files\Alwil Software\Avast4\AshoutXT.dll" could not be installed or loaded.

try reinstalling the software again, either do a repair if possible else use the avast uninstall tool to uninstall avast and then install a new copy

be sure that you have downloaded the most rescent version of avast before uninstalling
