Should I enable or disable cookies?

Now before the paranoia kicks in, let's be clear about something - they don't care about you specifically. Sorry, but you're just not that important. The sheer volume of data alone makes tracking any one individual a difficult task. What's typically interesting is aggregate data: the data that says things like X percent of the visitors to this website also visit that website.That's not to say that cookies can't be misused;it's just that it's typically a lot more work than it's worth.You can see what cookies you have and what they contain, but it's typically not particularly interesting. In Internet Explorer, hit Tools, Internet Options, the General tab, underneath Temporary Internet Files click on Settings. In the resulting dialog click on View Files. That'll bring up a list of all all temporary files, including cookies. I typically click on the Name column header to sort by name, and then scroll down to the point where the name begins with "Cookie:". There they are.Another approach is to download a Cookie viewing program to make things a little more readable. I've used Cookie Viewer from KarenWare.In either case, if you look at the contents of a cookie, they're typically very obscure. It's common practice to simply store a unique identifier of some sort and not much more. That ID usually makes sense only to the website that put it there, and effectively makes the cookie useless to others even if they could get at it.

You can control how Internet Explorer handles cookies to reduce any concerns you may still have. On the Privacy tab of Internet Options you can set the level of cookie handling IE should follow. That includes not only allowing, or blocking, all cookies, but also controlling third-party cookies resulting from things like embedded ads I mentioned earlier. And you can define an explicit list of sites from which you're prepared to accept cookies.

Super Cookie

Dangerous: Uses various techniques to resists deletion even when you clear your entire history they can remain hidden and reappear like a virus!

This is an example of a VERY persistent cookie. A cross between Super and Zombie types of cookie.
