What is DNS Changer?
In November 2011, the FBI seized control of rogue DNS servers used by cybercriminals to redirect PCs infected with the DNS Changer malware to a variety of money-making scams.
The FBI took immediate action to make the DNS servers harmless, but they remained online and 350,000 computers are still using these servers to connect to the Internet. On Monday, July 9, the servers will be shut down permanently. That means if you have computers that are using the rogue DNS servers, you will no longer be able to connect to the Internet.
Check the FBI website now to see if your DNS server is affected.
