Could it be the advertisement banner they have on the bottom of the page? (they have an advertisement banner at the bottom of all the pages)
As I understand it, advertisers are getting more sophisticated....you go to a certain page with advertisements on it, you dont have to click on the advertisement banners, they just automatically try to install something on your computer.
Can you still go to the page? If it wants you to install anything, can you refuse the installment?
