Manage your cookies

Ever wondered why websites “remember” your information when you go back and visit them again? You can thank cookies for that. Cookies are basically small amounts of data are saved as files on your hard drive for reference. This allows websites to identify you or your pc, which may lead to abuse such as tracking your surfing habits or acquiring sensitive information. So how do you manage cookies?

The bad cookies are placed by ad companies that pay for the right to place advertising on the sites’ pages (some sites also leave their own ad cookies). These files track your visits to pages that display their clients’ ads (or their own), and they may tailor the ads you see to your browsing history. Over time, cookies can reveal your browsing habits, though standard ad cookies, like those that DoubleClick uses, can’t attach a name to a specific surfing trail.

PC World says Block Spying Cookies but keep the helpful ones.
