Amazon.com home page doesn't load right.

Every time I try to buy something on Amazon.com, all of a sudden a new add pops up from some discount business trying to sell me the item at a lower price than what is on Amazon. This is infuriating and makes it practically impossible to place an amazon.com order. YES, my popup blocker is turned on. YES my security settings are at the maximum. This seems to me some kind of fraudulent hack -- the sites that come up are COMPETING with amazon. I called amazon.com tonight and reported this but I am dubious about any progress here. Thanks.
