video sites blocked?

Hi, I went on megashare.info, and there was this thing saying unsafe would you like to block? I clicked yes thinking it was malicious.

Now megashare.info and my mums QQ film watcher are blocked when trying to play the video.

I think something to do with flash. Any help fixing?

 

well you blocked from anything on megashare.info so you need to unblock it in order to get to what you need..
