Ubuntu Manual

A trojan named DNS Changer that resets the DNS Servers in a PC has prompted the US Goverment to temporarily shutdown the Internet to give time for web users in the US to remove the Trojan manually. Although a Trojan infecting a computer network is not new, its the first time in history that a Government is shutting down the web to remove one. This will affect some 3 million users in the US and more in the rest of the globe. All this means that now a Trojan is a serious business and the stakes are only going to get higher.
