What are cookies?
Cookies are small files, which are used for access to the Internet, that are stored on the computer, the mobile device, the tablet or other equipment of a given User.
Cookies are installed through a request by the server of a given web page to your web browser (i.e. Internet Explorer, Chrome, Safari, Mozilla) and are completely "passive" (they do not contain any software, viruses or spyware and do not have access to the information of the User hardware).
What are cookies used for?
Security and confidentiality
Cookies are NOT viruses. They take the form of simple text. They are not made out of code and cannot therefore be executed or execute themselves alone. Consequently, they may not be duplicated or copied into other networks in order to get started and copied once more. Since cookies cannot perform those functions, they cannot be regarded as viruses.
Most often, browsers have built-in privacy settings, which provide different levels for the acceptance of cookies, the period of their validity and their automatic deletion after a User has visited a given website.
