It's an advertising server (probably legitimate).
There's something about it here:
Adobe Flash Player has Stopped a Potentially Unsafe Operation | Internet Technology Blog
As your adobe flash player settings have stopped the communication, you probably need do nothing about it (It is possible to change the settings to allow it, but I see no reason why you'd need to - unless you want to see even more ads.)
Adobe flash uses so called "super cookies" to track your internet browsing. This is for advertising purposes, and is not really all that sinister - though some people (understandably) see it as a privacy issue and dislike it. You can tweak the adobe flash settings to allow nothing to be stored on your computer (but this may stop some internet activities working)
On a Linux computer, it's possible to divert all the flash junk to a temporary folder, so it's all lost when you close the browser - if you are really interested, I could probably find instructions - but it's not easy.
On a Windows computer, I'm afraid I wouldn't know how to start, or even if it's possible!
I guess the bottom line is that free websites couldn't run without advertising - and free sites are a whole lot better than pay-per-view
