To see all things with "C" appear after running several search with that letter at the beginning of a word is normal. To clear your browser history simply go up to the "Tools" link on the top of the IE browser window and click on that for the drop down menu there. At the bottom is the "Options" choice where you delete not only the browsing history but all offline content as well. You will have to re-enter passwords, user names, and email addresses later since those "Cookies" as they are called(text files stored on hard drive) will be deleted there. When you get back here you will have to login fresh. So don't forget your user name and password and any online email accounts or ???
