Last November the FBI gave details of the DNS Changer virus. This virus affects the ability to access the Internet’s DNS system, which means that Internet users would be rerouted to a fake DNS system, sending them to fake sites or places what are trying to sell fake products. The authors of this malware were arrested last year and at that time the FBI built new servers to redirect traffic away from those infected with the virus.
Since November there has been a movement to educate people about the virus so that people could have it removed before the servers go offline. Both Facebook and Google have taken measures to inform Mac and PC users that may be infected.
On Monday though, the FBI is retracting the servers that have been protecting people from the virus. Anyone that is still infected by the virus will lose access to the Internet until they remove the virus from their machine. It is expected that around 46,000 U.S. users will lose connectivity.
People affected by the virus aren’t out of luck though. If you’re having trouble with the Internet, the FBI recommends that you let your Internet service provider know that you’re having problems. Before removing the virus, back up your files on an external hard drive to ensure that you don’t lose any essential items.
Programs like Windows Defender Offline, MacScan and PowerEraser can be used to scan your computer for the existing virus. A complete list of programs that can get rid of the virus can be viewed at the DNS Changer Working Group website. If you already have these tools on your computer you can run a scan to remove the virus. If not, call your Internet service provider for advice on how to proceed. Once the scan is complete you may have to reset your router or modem settings.
