Time Warner Cable has received notification about industry-wide malicious online traffic, which we have identified as impacting a small fraction of our customers. If you received a notification from Time Warner Cable advising you that your system has been impacted by this industry-wide attack, your computer or another computer on your network may be infected by malicious software known as "DNSChanger."
DNSChanger redirects your internet traffic to alternative Web sites, most commonly redirecting advertisement traffic to sites controlled by the malicious operator. This means your Internet browser is pulling up different sites than the one originally intended by the Web site operator. DNSChanger does this by sending your computer's Domain Name System (DNS) traffic to servers under their control. Also, this malware allows infected computers to be controlled remotely (i.e., by another computer on the Internet known as a "command and control" server, or a C&C server). Details about this malware attack, and how your system may have been infected, can be found on the following FBI and Department of Justice Web site: http://www.fbi.gov/news/stories/2011/november/malware_110911/dns-changer-malware.pdf
