I just read an article talking about so-called “supercookies” and “evercookies” — cookies which are supposedly impossible to delete, and left without the computer user’s permission or even knowledge. What are “supercookies”? What are “evercookies”? And how can I protect my computer from them?

Supercookies and evercookies are the result of a website owner’s desire (or more often, the desire of the advertising networks used by websites) to accumulate data about computer users and the sites they visit — even those users who disable or clear cookies in their browser regularly.
Bottom line: clearing cookies isn’t enough — not nearly enough.
And there may be nothing that is.
