Addin Outlook 2007

Since the last update, when I start Outlook 2007 I get a message “Serious problem with ‘avast! addin’, please disable or update this addin”

My environment:
Windows Vista Home Premiun SP2
Microsof Outlook 2007
Avast Free 7.0.1456

Any advice?

There is a bug in the 1456 version. They’re working on it.
Right now, the better is to disable the plugin. Sorry for the inconvenience.
