When I use Google to search for something, I get an automatic "
pop-up"  of what Google thinks that I want to search for. For example
if I
want to find something on " lacerations " , the word  " lacrosse "
will automatically appear where I am trying to type. This is very
annoying. How do I stop this from happening?

I am going to assume you are referring to entering searches at
Google.com as opposed to the Google Toolbar.  Another assumption is
that you are using
Internet Explorer.  If this is incorrect, please let me know.

To delete the keyowrds that keep popping up:

If you are using IE 5 or higher, you have a couple of options for
removing the stored keywords.  You should be able to click in the
search box and get a "drop down" box to appear, listing all the things
you've searched for in the past at Google.

Using the arrow keys on your keyboard, highlight the entry you want to
remove (or you can use your mouse).  Once the term is highlighted,
simply push the Delete button on your keyboard and it will disappear.

To delete ALL the search terms, goto "Tools" then "Internet Options"
then choose the tab labeled "Content".  Click on the button which will
make the AutoComplete Settings window appear. In it, click on the
"Clear Forms" button to delete all your stored form entries.  This
will also remove ALL form entries that you may have stored as well,
such as login names, address information you may have entered into
forms, etc.

To stop this from happening again, return back to the AutoComplete
Settings window.  Uncheck all the fields (Web Addresses, Forms, User
Names and Passwords on forms) that you no longer want to store.  For
the search window on Google, it would be the Forms option.


Thanks for your question and if you need any additional clarification,
please let me know.

Content > Auto Complete > Unselect Forms check button
