How can I delete my search word permanently from google tool bar or any other search engine? please help?

What you are trying to clear is "autocomplete" This is what you do... Goto Internet Explorer, Options, Under the "Content" tab, Select "AutoComplete" and clear all autocomplete. That will do the trick. Have fun & start surfing using Chrome if you need to surf 'without leaving trails on the computer'. Chrome's got an Incognito mode which does this. That said however, remember that Incognito only stops leaving trails on the computer but whatever you do online can still be traced back to you as you're still going through your Internet Service Provider. Get Chrome at http://www.google.com/chrome

go to Tools > Delete browsing history and there will be a list of Temporary internet files Cookies History Form data Saved passwords I think its form data. So click delete forms next to it and be done with it.
