What are cookies?

A cookie is a small file that is stored on your computer´s hard drive when you visit a site using cookies. The cookie file can contain any data the site´s designer chooses. For example; preferred screen resolution, language or even login name and password. The information stored in a cookie can only be accessed by the site that created the cookie. The normal use for cookies these days is to store surfing behavior or previously visited sites, so that advertising can be targeted at you and your specific needs.  

What are session cookies?

There is no file stored, and the information in the session cookie cannot be accessed the next time the site is visited. For example; shopping carts, menu selections or form fields.  

Does cookies contain viruses?

No, the cookie files are completely normal text files, and hence they cannot perform any malicious actions.  

Does cookies consume hard drive space?

No, the files are very small, compared to other web based files (such as images, and the pages themselves). All modern browsers have a limit to how many cookies can be stored on your computer, and you needn´t be worried about the space they consume, as this is handled by the browser. You can safely allow cookies to be stored on your computer without risking running out of space.

How do I remove cookie files already on my computer?
