In Google Options unchecking "drop-down search history" may prevent this.
Also, you can left click "Clear Search History" in the Google drop-down menu to clear the current Search History.
When I use google to search, google somehow saves my previous queries. For example if I want to do a search for "disk", I get a "Drop down box" which shows me my previous searches that start with "d". I do not want my previous searches to be provided.
I have deleted all my cookies, all my temporary internet files and this does not help.
Is it possible that this information is contained in the "index.dat" file?
I am using Windows ME and IE 5.5
