Nothing out of the ordinary at either of them for me either. Maybe your machine has succumbed to a sneaky piece of Adware being installed on it without your knowledge. Easily found and removed if you use tools like AdAware-SE, or Spybot Search and Destroy.
Im useing firefox 2 with no add blocks (for some reason the downloading of the add bloker seems harder than putting up with the adds!) and I can see excacly the same amount of adds as have been since I joined avsim..
Your on fast internet anyway, its us "56kers" that suffer most from adds... (unless you downloaded a hell of alot and were slowed down to dial up )
