Salut,
Vu sur le site d'Avast ici:
"Q: The provider of On-Access Scanner called Outlook/Exchange is still waiting for a subsystem to start. Is anything wrong?
A: No. This provider is running only when MS Outlook (not Outlook Express!) or MS Exchange is running. If you don't use any of these programs, the provider isn't running either. "
Cela ressemble à ton pb... apparemment, c'est normal.
Cela étant, je serai rassuré que quelqu'un d'autre donne son avis sur la question.
