How can I delete my yahoo name?

How can I delete a seach name from my Yahoo search box so there is no way to track / name doesn't appear next?

• I do not want the automatic recognition of past seaches to work in my Yahoo search. Today what happens is that when I type any word that starts with the letter that my previous search had, it prompts that word. I do not want it to happen. How can I delete it?

• Answer:

  In Internet Explorer, click the "Tools" link at the top of the window then select "Internet Options". Click on "Content" tab at top. Under "Personal Information" on the bottom half of the window click "Auto Complete". Uncheck "Web Addresses", "Forms" and "User Names & Passwords on Forms". That prevents the Search History from being kept. To erase what's already there then below that click the "Clear Forms" and "Clear Passwords" buttons. Then click on "OK", click "Apply" and click "OK" again to close the window and save your settings. If you are using Firefox, click "Tools", then "Options" then "Privacy" then "Saved Forms". Click "Clear Saved Forms" to erase the saved data then uncheck the box in front of "Save information I enter....." Click "OK" to close the window and save your settings. If you wish to delete recent searches from the Yahoo! Search box on the Yahoo! Toolbar, click the pencil icon to the left of the Search Box then click "Clear Recent Searches".
