Answer

Most internet advertising exchanges use cookies to keep track of which ads have been displayed to a particular visitor. These cookies do not acquire or collect any personal information about visitors (such as name, address, phone number, or email address), and the technical information they do temporarily store (such as geographic location, browser type, and IP address) is used solely for the purpose of targeting ads and measuring a given ad’s effectiveness. Nonetheless, some security programs flag such cookies as “adware” and/or mistakenly report cookie placement as an attempt to download software to the user’s computer. If you are uncomfortable with the use of cookies to temporarily store non-personal information, you can delete the cookie or alter your browser’s security settings to prevent it from accepting cookies.
