Keep Spyware OUT! Block Ads! Speed up Webpages!

I've been using this for a long time.....it's a very simple solution. when you visit a webpage, and there is an ad located at ad.doubleclick.com, your computer looks to itself for the page instead of the internet, and you see no ad. Check it out, I love it.
