DNSChanger, a form of malware, redirects your Internet traffic to alternative web sites allowing the malicious operator (and alleged criminal) to control the customer’s Internet experience. A common method is to redirect advertisement traffic to sites controlled by the malicious operator. This malware can also allow infected computers to be controlled remotely. Details about this malware, how it can attack customers, and how your system may have been infected, can be found on the following FBI and Department of Justice website.
DNSChanger malware causes a computer to use “rogue,” or bad, DNS servers in one of two ways. First, if the malware successfully infects the customer’s computer(s), it changes the computer’s DNS server settings to replace the ISP’s good DNS servers with rogue DNS servers operated by the criminals. Second, if the malware infects a router or gateway device on the customer’s network, all computers located behind the router or gateway device within your network could be controlled by the malicious operator. Therefore, these changes may impact all computers on your network, even if those computers are not themselves infected with the malware.
There are many forms and versions of this malicious software and no utility can effectively detect and remove all versions of this software from all operating systems at this time. Cox recommends taking the following actions with these free tools as they may be effective in removing the malicious software:

If these tools are unable to remove the malware, as a precaution to protect your privacy and data, the Department of Justice with the assistance of the FBI and Cox, recommend that you update your master boot record and reformat your hard drive or take it to a local repair shop to have this done.

If your DNS settings have IP addresses within any of the ranges listed below, you must re-configure the device and secure the router / gateway with a strong password. See Cox Password Requirements for tips.
