About DNSChanger: 

The malware, known as the “DNSChanger Trojan” quietly alters the host computer’s Internet settings to hijack search results and to block victims from visiting security sites that might help scrub the infections. DNSChanger frequently was bundled with other types of malware, meaning that systems infected with the Trojan often also host other, more nefarious digital parasites.

Earlier few guys ware busted for using the Trojan to control more than four million computers in over 100 countries - including an estimated 500,000 in the United States. Investigators timed the arrests with a coordinated attack on the malware’s infrastructure. The two-pronged attack was intended to prevent miscreants from continuing to control the network of hacked PCs, and to give Internet service providers an opportunity to alert customers with infected machines. Computers still infected with DNSChanger are up against a countdown clock. As part of the DNSChanger botnet takedown, the feds secured a court order to replace the Trojan’s DNS infrastructure with surrogate, legitimate DNS servers. But those servers are only allowed to operate until March 8, 2012. Unless the court extends that order, any computers still infected with DNSChanger may no longer be able to browse the Web.
