Yahoo is doing the same, and often has better search results because Google's are like an over-congested highway.
One of the things Google does is highlight those sites that might be a dangerous security breech for your computer. In Google, a risky link takes you to a warning page saying "This site may be harmful to your computer."
But Yahoo automatically removes those threats from the search results. It lets through those that may have a link to downloads which may be spyware tricks. You'll stay safer in Yahoo if you look for the red warning triangle before opening such sites through a web search.
The other nice thing Yahoo has figured out, is how to let you know if a searched site has a nasty habit of using people's email address for spam. Now that's letting technology do something wonderful for us.
I feel safer already. Let me know if you Yahoo !!
