The problem is really an old problem. It will have an effect on people who have not verified the DNS settings on their computers.
The DNS depends on where you live. You would want a service near you for best results. But the issue is to make sure it is a valid service.
Who've not verified their DNS? More like for those that have not FIXED their DNS!
DNS depends on what ISP you have, or if you have changed it yourself. If viruses/malware have changed your DNS, it is your own problem not the ISP's problem. If you have elected to use Google DNS or OpenDNS, it is your business.
Therefore, for those infected with the rogue servers are considered zombies, in which will be deactivated of Internet access as of Monday! This is the attempt to stop the DNSChanger cybercriminals, to help track down and investigate them.
Whomever is keeping the DNSChanger botnet alive is being tracked down.
