IE 6 Address bar-can't delete an address

[Persistent address]

I have an address that pops into my address bar via the
auto-complete when I type in another address that begins
with the same letters. I've cleared the history, cookies
and internet cache, but it won't go away. AdAware won't
even get rid of it. How can I get rid of this persistent
address?

Removes the URL's from the Address Bar drop-down list without deleting the
Internet Explorer History.

Thank you for the suggestion; I installed the utility, but
the address is still there. Is there some kind of malware
that puts addresses in the drop-down list and doesn't
allow erasing them?
