Just when I thought I'd heard every possible ruse for criminals to get you to switch on your computer and let them in... one came up today from a Highway associate who was telephoned by someone from the Government CyberCrime Unit and told his email was being used by criminals for 'wrong purposes'.  There is a National Cyber Crime Unit (part of the National Crime Agency) but in no way would they telephone you and ask you to switch on your computer so they could 'show you what to do'.

Again, NEVER, EVER ALLOW ANYONE TO HAVE ACCESS TO YOUR COMPUTER with the exception of one of our Highway technicians.
