Avast throws 'malware detected' Bejeweled on Facebook

Does anyone else have same problem, my Avast, every time I am in Facebook and go to play Bejeweled it says ‘Malware URL detected, …’, it seems to be with the ‘adverts’ that come with Bejeweled Blitz, they keep throwing them up whilst trying to play the game, can Avast not work in with this ‘app’ on this… never had this problem before and have had Avast Premier for a few years now, Suggestions please…
