Random Redirect to Yahoo AssociatedContent

I have a niche technology site running on Wordpress and recently I have been notcing some very strange behavior. Whenever I tab on an article I will be redirected to Yahoo’s associatedcontent website. This has happened twice in the past few days and I was wondering if I’m a victim of some kind of attack? I’ve done a little reading on click jacking but I’m not really sure if this is click jacking. Anyone know what might be happening here? Is there a way to check if my site is vulnerable to any of these shady tricks?

anyone with info on this?
