I've been using Adblocker Ultimate for over a year, I installed it and after that it took care of the never ending ads that the internet is full of. It does it so well that its easy to forget its even there.
Hadn't had an unwanted popup window in such a long time so I was surprised when suddenly there was a pop up window from Adblocker telling me it had block 10,000 ads since I had installed it and asked me if I would rate it.
I think 10,000 blocked ads is outstanding and if I could I would give it 10 gold stars. ;o)
