"Do you accept cookies?" We all see the message, almost every day - and mostly we click 'yes', without batting an eyelid. Not many of us, however, fully understand what cookies do - or how accepting some of them can open the door to their more malicious relative, adware. Take five minutes to watch our explainer video.

What are cookies and adware?

Most cookies are designed to be convenient and are used to remember login details and complicated passwords.

Some cookies, known as ‘tracking cookies’, track your online habits and provide personal information to third-party advertising networks who subsequently bombard you with unwanted ads.

Adware is a form of malicious advertising that throws up unwanted adverts.

It can also change the browser's home page and the default search engine, inject rogue results into search pages and rogue advertisements into legitimate websites. 

For more information on the associated risks and online safety tips for parents and carers, watch our explainer video, available to those with a National Online Safety membership.
