DNSChanger Malware
In November 2011, the FBI replaced rogue DNS servers with clean servers to prevent millions of Internet users infected with the DNSChanger malware from losing Internet connectivity when the members of a ring where arrested during Operation Ghost Click. However, the court order allowing the FBI to provide the clean servers is set to expire on March 8, 2012. Computers that are infected with the DNSChanger malware may lose Internet connectivity when these FBI servers are taken offline.
