I'm getting it when I go to a few sites, mlb.com mostly. If you go to some mlb.com pages, you'll occasionally get this one, I believe as a redirect. I've searched around and there's almost nothing about it around.
I'm not sure if it's malware but it bares a very strong resemblance to malwarish pages. It's a .be domain and that's Belgium. A Belgium site trying to update your flash can't be good.
