An estimated 500,000 computers worldwide are infected with malware (spyware) called “DNSChanger.” DNSChanger modifies the DNS settings on computers and routers, causing them to use malicious servers that redirect you to fake and potentially dangerous web sites.
Last November, the FBI arrested the people who ran the operation, seized the malicious servers, and temporarily put up surrogate servers in place of the malicious ones so that infected computers could continue to access the Internet. On July 9, 2012, the government will remove those temporary servers, at which time any computers that are still infected will lose Internet access.
