Avast must have updated last night and now the Network shield is blocking www.hulu.com/player.swf as a malicious site.
It could be a shockwave exploit perhaps.
Though I can’t really check it out on dial-up, another topic on this site http://forum.avast.com/index.php?topic=43295.0.
Hello,
fixed in currently released update (090311-1), thank you for info.
