Erasing history

How can I erase my history properly? I mean, I do TOOLS - INTERNET OPTIONS - CLEAR HISTORY/DELETE COOKIES/DELETE FILES, but there are few sites that my computer permanantely remembers (I type a letter and get a site below my bar, but I deleted history)? How to get rid of those?

Jam it back in, in the dark.

I know I've visited those sites, and they are still in my history, even after I erase the history :eyebrow:

Double Post:
It's just like the google thing, if you searched for something, it will remember it, even if you delete cookies, history, all stuff. But you can delete the google thing with DELETE key, and you can't with my history.

There's nowhere I can't reach.
