What the ‘Internet doomsday’ virus is and how to fix it
Posted by Abdul Alim
Washington Post: Thousands could lose access to the Internet on July 9 due to a virus, DNSChanger, that once infected approximately 4 million computers across the world.
The Federal Bureau of Investigation first gave details about the virus last November, when it announced the arrest of the malware’s authors. The virus, as its name indicates, affected computers’ abilities to correctly access the Internet’s DNS system — essentially, the Internet’s phone book. The virus would redirect Internet users to fake DNS servers, often sending them to fake sites or places that promoted fake products. Once the FBI shut down the operation, it built a safety net of new servers to redirect traffic from those infected with the virus.
But that safety net is going offline next Monday meaning that anyone who is still infected with the virus will lose access to the Internet unless they remove it from their machine.
To see if you have the virus, you can head to any number of checker Web sites such as theDNS Changer Working Group or the FBI itself to either enter your IP address or simply click a button to run a check against addresses known to have problems. With any luck, you’ll be free and clear and won’t have to worry about the problem any further.
