I have it open here right now. It's an ad that cycles through 3 pages.
1. 'Shop Online' with shopping carts flanking the text.
2. Pictures of stuff you can presumably buy (A coffee mug, towels, a camera and a PDA/Smartphone)
3. Text that says 'Click to get discount!'
At least that's the one that opened the 'Antivirus check' for me here.
