Today Google announced it would be leading a campaign to notify users whose PCs were infected by the DNSChanger malware. The malware was part of a scam that came to light last November
when the U.S. Department of Justice accused seven Estonian and Russian men of orchestrating several different kinds of Internet fraud schemes. Users were infected with DNSChanger after they clicked malicious links
or downloaded tainted software.
The malware sent infected computers to DNS servers that redirected millions of victims to websites they had never intended to visit.
