Question: What are cookies and what are they used for?
Answer: Cookies are text files that Web servers place on your computer. The server uses the file to identify you when you return to the site. Cookies not only aid websites in identifying repeat visitors, they also allow you to customize your browsing experience. For example, when you log into a password-protected website, a cookie from that website helps the site "remember" you and your site preferences so you don't have to re-enter the password every time you go to a new page on the site.
Cookies also allow servers to monitor your browsing habits, including how many times a site is visited, as well as which pages you view. The Privacy Manager in Virgin Media Security gives you control over how much information Web sites record about your browsing habits. Before a cookie is placed on your machine, the Privacy Manager feature checks to see if the cookie is from an untrusted web site. If this is the case, the cookie will be automatically removed.
