What is a cookie (or Adware Cookie) ?
Cookies are pieces of information that are generated by a Web server and stored on your computer for future access. Cookies were originally implemented to allow you to customize your Web experience. However, some Web sites now issue adware cookies, which allow multiple Web sites to store and access cookies that may contain personal information (surfing habits, usernames and passwords, areas of interest, etc.), and then simultaneously share the information with other Web sites. Adware cookies are installed and accessed without your knowledge or consent. Worst case scenario: This sharing of information allows marketing firms to create a user profile based on your personal information and sell it to other firms.
