You should be able to go up to the area on the page where you toolbars and right-click.  Ensure the search toolbar is "checked".  Once checked, you'll see the magnifying glass and you can use the drop-down to choose your search engine.  Hope this helps.

jenni.p,

locators.com is a search engine hijacker (spyware).  You will need to get Ad-Aware and Spybot from the following sites:

www.lavasoftusa.com  Ad-Aware

http://security.kolla.de/  Spybot

Download these programs, install them, update them to the latest definitions, then run them and allow them to remove all of the garbage they find.
