    How to delete cookies - All browsers. Cookies - small files of websites you visit, they put up house on your computer and it doesn't seem like it, but they can be very useful. They are used to "remember" usernames or content or a shopping cart on the websites you visit.


    The next time you visit the site, it reads the cookies on your PC and uses the data it contains to populate the username field in the login window or the shopping cart on an online shopping site. However, cookies can also be used for less innocent purposes, including user tracking on the web. Here we will show you how to delete cookies.



    What are tracking cookies?

    Cookies are small files that are placed on your computer, placed there by the websites you visit, containing data about what you have done on the site. However, in addition to the website itself that places cookies on your PC, some sites allow advertisers to place their own cookies, so-called "third party cookies". These are tracking cookies.

    Recent versions of Safari block third-party cookies by default, but if you are using another browser such as Chrome or Firefox, some may be scattered across your PC. These third-party cookies are the reason why, when you search, for example, for a brand or an article on Google, you see advertisements based on the search performed.


    Do I have to worry about tracking cookies?

    Are tracking cookies harmful? In a word, yes! Mainly, cookies are mostly quite harmless. And proprietary cookies are very useful: without them the web browsing experience would be very limited. However, if you are concerned about privacy or do not like being tracked by advertisers, you should be concerned about third party or tracking cookies.



    In addition, some tracking cookies are also used by some malware. So, if you have downloaded malware, even if you have eliminated the browser extension, toolbar or other visible signs, you should look for and remove cookies as well.

    How did they arrive on my PC?

    By default, most web browsers allow websites to place cookies on your PC because, in most cases, they are useful and in some cases even necessary for a site to function properly. Most browsers allow both proprietary and third-party cookies.


    How can I avoid receiving tracking cookies?

    Most web browsers have a setting that allows you to request that websites not follow you. However, there is no guarantee that the websites will comply with this request. And, of course, sites hosting malware will ignore it. Apple's Safari has an option in Preferences> Privacy that allows you to "Prevent cross-site tracking" and is enabled by default, preventing third-party cookies from being stored on your PC.

    Therefore, the use of Safari is a way to avoid the tracking of cookies. You can also use DuckDuckGo as your default search engine. Unlike search engines, it does not log or track your search queries, or pass data on to third parties.
