While I went on to the Daily Puzzle page through the menu (Learn -> Daily Puzzle) I saw a file download dialog box. Please see the image. Any body else noticed this? Can it be a virus? Or what?

I am sorry. First time I uploaded the image. I didn't realize that it is too large.

not a virus, but weird. do you have flash installed?

Looks like an ad server isn't configured properly and forced a stream download of the SWF instead of sending it to be rendered in flash.
