In Internet Explorer, Go to TOOLS/Internet Options/General and you can remove a lot there. In the Advanced tag, find and tick Empty TIF files when browser is closed. Make sure all cookies are checked over and deleted. You will have to track down and remove all Index.dat files. I think CCleaner will do that for you. Cleaners can damage your system so be sure what you tick to clean.
In Firefox, you have similar options on the Tools/Options/Privacy page.
Google will also record every page you visit, so if you have a Google Account, find your account and delete everything you don't want. This is there to 'speed up' your searching, but there should be an option to turn this off.
Sorry I am not as specific as I could be, but am going off memory at the moment. If you have further questions, just come back.
