History clean up

Hello,

I usually use IE 7 for web surfing but i heard that firefox3 is a lot faster and has more features so i got it. I changed the settings on CCleaner so that it will only clean IE and not FF. I ran it and it did not delete the history in IE. Can some one help me with this? Thank you.

I have a related problem. Recently I have noticed that when I enter search terms in IE7 or Google Toolbar and then run CCleaner, CCleaner no longer deletes the search terms from the search boxes in IE7. How can I get CCleaner to delete these search entries along with history, etc.?
