Cookies are files, typically text files which are stored on a user’s device. They are made to contain data specific to the user or website, and can be accessed either by a web server or the users device. Cookies cannot themselves harm your computer in any way. Cookies allow the web server to deliver a web page “suited” to the user, or the web page itself can contain a script which is reading the data in the cookie and so is able to carry information from one visit to the website to the next website.
Typically what this means is that cookies are used to remember logins and keep track of user settings on websites, this information might include the name of the site, particular products being viewed, pages visited, etc. Cookies can be used to track your movement on the Internet ONLY if a site is aware of the cookies and is designed to use the specific cookies. Because of their use in tracking online activity, many feel that this constitutes spyware. Most antispyware applications, including SUPERAntiSpyware, detect tracking cookies in one form or another.
Cookies are not blocked by SUPERAntiSpyware because they are required for most web functionality. Cookies will come back every time you surf the web, and can be cleaned by running a Quick or Complete Scan.
