To find your cookies... Look in windows\cookies, or if you use logins for your computer, windows\profiles\\cookies.

Some cookies are good... like the one IW puts out there after you log in. Some are bad... like those for spyware and other malware. You can probably nuke them in most cases without any more hassle than simply having to log in again.

Some browsers may store the cookies elsewhere; I use IE, and that's where it puts them. If you want to really get rid of them, go to Tools, Internet Options and click on the Delete Cookies button. Again, that's IE; other browsers (and earlier IE versions) may not have such a feature.
