Greater Manchester Police has been unable to carry out checks on criminals and suspect vehicles since the virus entered its computer network on Friday. Officers have been warned against using unauthorised USB flash drives a common method for the Conficker worm to enter an organisation. The virus is not destructive and no data has been lost but due to the speed it has spread we have temporarily cut off our access to the Police National Computer and other Criminal Justice systems to prevent further spread. The public has not received any difference in the level of service they have received as a result of the virus infection.”]
