A cookie is a piece of information that is stored on your PC in order for information from websites to be stored. These are saved as small text files that are kept in a cookies folder on your hard drive. Cookies themselves are not harmful and cannot contain viruses or spy on the contents of your hard drive.
These text files normally contain the following information:
- The web server the cookie originates from
- The lifespan of the cookie (this can be permanent or expire after a specific amount of time or when the browser is closed)
- A unique reference, which allows the cookie to be recognized by the web server
Cookies are used for various purposes, from authenticating users to maintaining specific information, for instance when using online shops.
Some sites require cookies to be turned on in order to function correctly, typically if using online banking or online shopping.
