Avast anti-viris problem.

my Avast antiviris on my computer keeps acting up every 10 minutes.saying "threat has been detected" when i am only on facebook.now i'm wondering if i'm being hacked or something.

my avast has been doing real good to me every since i got my laptop in July 2011. hasn't failed since.
