The UK's leading experts on Cyber crime are meeting in Liverpool this week for a three-day summit. "Cyber UK" is organised by the National Cyber Security Centre which was set up last year by the government, with the aim of making the UK the safest place to live and do business online. Cyber attacks can be against individuals, companies, or governments. Delegates will explore ways of deterring would-be attackers. In recent years, You & Yours has heard the stories of countless victims of online fraud and scams. We examine what can really be done to protect ordinary people from the growing threat online.

We hear expert advice on how to avoid spurious charges like this.
