Cookie Spy SE is the complete manager for all those Cookies installed by web sites you visit.  An easy to use interface lets you delete and permanently block Spyware Cookies or allow the ones you want to keep such as those that remember who you are when you log in to a site.  Once a site is blocked you will never receive a Cookie from that site again.  The Filters Lists makes it easy to change and/or remove those cookies you've blocked or allowed.

Some Cookies are harmless and in fact helpful, but more sites and programs use cookies to get your email address, shopping habits and other personal details.  It's not uncommon for computers to have hundreds and even thousands of Spy Cookies installed and most often when you delete them they're installed again when you revisit the site.  Cookie Spy SE allows you to permanently block those you don't want, while still allowing those that you find useful.
