New download of MRU blaster

At the risk of looking dumb I am posting for help if possible. Got our new computer ans switched from aol. Never had this issue before when I used their search. But now having to use MSN and Yahoo searches it saves my search inquiries in a drop down box that does not show up all the time just if you start typing something close to what is in it (I think). I have tried the temp file and clearing history and cookies, When I saw this blaster I thought it would clean this up but these items are still listed in the search boxes. Any ideas on how to get rid of these and stop it from happening? Thanks for your help

 

IE > Tools > Internet Options > Content tab > press 'Autocomplete' > press 'Clear Forms'.

Then uncheck any undesired options.

Cheers,
