Internet dialler scams are when the computer settings are changed on a person’s computer so their internet connection is re-routed via an expensive telephone line.
It can happen when a person opens a spam email, clicks on a pop-up box or visits a pay-per-view website, and downloads the software that makes this change to their computer.
If fraud has been committed, report it to Action Fraud.
