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.
