Clean your computer by July 9 or lose internet access: Google warns

“Your computer appears to be infected” – if you’re among the half-a-million users who might have seen this warning appear on their PCs recently, you’ll be in for a nasty surprise come July 9.
Unless users with infected computers clean up their devices by then, they risk losing internet connectivity, search engine Google is warning as part of a new campaign to rid the world of the dreaded DNSChanger malware.
Starting this week, Google says it is “undertaking an effort to notify roughly half a million people whose computers or home routers are infected with a well-publicised form of malware known as DNSChanger.”
The Domain Name System (DNS) translates familiar web address names like google.com or emirates247.com into a numerical address that computers use to send traffic to the right place. The DNSChanger malware modifies DNS settings to use malicious servers that point users to fake sites and other harmful locations.
DNSChanger attempts to modify the settings on home routers as well, meaning other computers and mobile devices may also be affected. Google says that any users of its search tools who are detected redirecting to DNSChanger’s substituted domains will see the stark warning splashed on top of their search results page.
“We’ve… started showing warnings via a special message that will appear at the top of the Google search results page for users with affected devices,” Google warned on its online security blog (http://googleonlinesecurity.blogspot.com/).

You can also test to see if you are affected by visiting the following DNSChanger Check-Up site,http://www.dns-ok.us/
If this Check-Up site indicates that you are affected by DNSChanger, then visit http://www.dcwg.org/fix/ for information on how to address this problem.
Google, however, acknowledges that it might not be able to reach all of its target audience of affected users with this current campaign. “While we expect to notify over 500,000 users within a week, we realise we won’t reach every affected user. Some ISPs have been taking their own actions, a few of which will prevent our warning from being displayed on affected devices,” said Google's warning.
As many as half the users affected by DNSChange do not speak English and had not reacted to warnings already issued by the FBI and others, Google believed. “At the current disinfection rate hundreds of thousands of devices will still be infected when the court order expires on July 9th and the replacement DNS servers are shut down,” Google said.
However, July 9 remains a binding date, says the search engine, and warns that devices that remain affected on that day may experience Internet disruption. “At that time, any remaining infected machines may experience slowdowns or completely lose Internet access,” it warns.

What is the DNS Changer Malware and how to clean your computer
What is the DNS Changer Malware?
On November 8, the FBI, the NASA-OIG and Estonian police arrested several cyber criminals in “Operation Ghost Click”.
The criminals operated under the company name “Rove Digital”, and distributed DNS changing viruses, variously known as TDSS, Alureon, TidServ and TDL4 viruses.
You can read more about the arrest of the Rove Digital principals here, and in the FBI Press Release.
What does the DNS Changer Malware do?
The botnet operated by Rove Digital altered user DNS settings, pointing victims to malicious DNS in data centers in Estonia, New York, and Chicago.
The malicious DNS servers would give fake, malicious answers, altering user searches, and promoting fake and dangerous products. Because every web search starts with DNS, the malware showed users an altered version of the Internet.
Under a court order, expiring July 9, the Internet Systems Consortium is operating replacement DNS servers for the Rove Digital network. This will allow affected networks time to identify infected hosts, and avoid sudden disruption of services to victim machines.
