What is DNS?
Domain Name Service (DNS) is an Internet Service that converts user friendly domain names into IP addresses that computers use eto identify each other on the Internet. For example www.talesfromthebits.com is the user friendly name. The IP is 220.127.116.11. It is much easier to remember the name than the IP address!
What DNSChanger malware is doing to my computer?
Criminals learned that by controlling the user’s DNS they can control what sites the user visits on the Internet. They can create fake web sites and redirect the unsuspected user to these sites in order to gather personal information or to display fraudulent web sites or to install silently more malicious software to the user’s computer. The FBI has uncovered a network of rogue DNS servers and has taken steps to disable it.
