On November 8th of last year the FBI’s “Operation Ghost Click” shut down an Estonian Crime Ring that had developed malware which infected millions of computers worldwide. Since March of this year the FBI has operated a set of clean DNS Servers to assist victims affected by the DNSChanger malicious software. This solution was only temporary, providing additional time for victims to clean affected computers and restore their normal DNS settings. These clean DNS servers will be turned off on July 9, 2012, and computers still impacted by DNSChanger may lose Internet connectivity at that time.

If you believe your system may have been compromised by the DNSChanger malware (also called the TDSS, Alureon, TidServ and TDL4 viruses) then you would need to change your DNS Servers to your ISPs (Internet Service Provider’s) DNS Servers or configure your computer to use OpenDNS or Google’s Public DNS. You can go to DCWG.org to test if your computer system is infected, and to get instructions on how to change your computer’s DNS Servers.
