Learn more about the DNSChanger virus, a form of malware that may be negatively affecting your domain name system settings.
DNSChanger Malware Information Cox Communications is dedicated to protecting the Internet experience of our customers. We notify customers when their computer systems may be infected with malware.
DNSChanger, a form of malware, redirects your Internet traffic to alternative websites, allowing the malicious operator 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, 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, Domain Name System (DNS) settings in one of two ways. First, if the malware successfully infects the customer’s computer(s), it changes the DNS settings to replace the good ISP settings with rogue settings that are then operated by the malicious operator. 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 from all operating systems. Cox recommends you consider using the following free tools for removing the malicious software:
