A couple of people have said the ad is no longer happening...
Here's an explanation of how this happened in case you are curious.
MacRumors outsources ad sales to a 3rd party network
3rd Party Network negotiates ads with Companies.
Bad Company #1 signs on for ads... and gives them a Flash Ad for a fake-site. This ad looks normal when loaded in the U.S. by the Ad Network people. Ad is placed into the rotation.
The ad has certain criteria where if the viewer is in a certain country (norway, australia), it triggers the redirect to send them to spamware-site.
Meanwhile, myself and the ad networks have a hard time tracking them down do to this erratic nature.
Again... if someone has one come up again... please post here.
