We're not sure what's going on in here, but there's something wrong at AMD's user discussion forum, located at forums[dot]amd[dot]com.
If you visit the site (and please don't visit it right now), you get a WMF exploit sent to you right from the front page.
When inspecting the source code, you'll see that at the bottom of the HTML is an encoded IFRAME directive:
When decoded, that translates to http[colon]//toolbardollars[dot]biz/dl/adv586.php.
How did it end up on the AMD site? We have no clue. But we have informed relevant people, so hopefully this will be resolved soon.
