Do you want to stop google from saving your search queries and search google in a more secure manner ??
Here is a small wonder called scandoo, which allows you to search google in exactly same manner as the original google. But it also scans the individual pages in the search results and warns you if any of them contains malicious items in it!! That is its wonder !!
You have other benefits with this also:
You can hide yourself from google and stop google from saving your ip and search keywords.
You can stop opening offensive content (kinda NSFW) at office. This displays a X sign near the result, if the site contains any offensive material. Also, this sites gives you an option to select various categories which should be considered offensive.
You also have yahoo search and msn search here. (But, every search is not integerated with the other one)
