Mac OSX 10.7 : Web Agent doesn't start

Hello
Since 2 days, when I start my Mac, Avast says me “Impossible de détecter 1 ou plusieurs boucliers, vous n’êtes pas protégé” (impossible to detect 1 or more agent, you’re not protected).
And the web agent and the mail agent don’t start.

I’ve desinstalled Avast, and re-installed it, but I’ve always the problem.
My Avast version is 9.0

Could you help me ?
Thank you very much.
Eric
