what does it do?

This DNSchanger alter your DNS settings, pointing victims malicious DNS in data centers in Estonia New York, and Chicago.If your system is infected, your computer may be accessing malicious DNS servers that would give fake answers, alter your searches, and promote fake and dangerous computer products. In addition, an infected computer will show you an altered version of internet sites. There are many ways a machine could have become infected with the DNSChanger virus including not applying operating system, browser, and browser plugin security updates.

DNSChanger malware causes a computer to use rogue DNS servers in one of two ways. First, it changes the computer’s DNS server settings to replace the ISP’s good DNS servers with rogue DNS servers operated by the cyber criminal. Second, it attempts to access devices on the victim’s small office/home office (SOHO) network that run a dynamic host configuration protocol (DHCP) server.

On July 9, those malicious servers that your computer may be communicating with will be shut down by the FBI. If you are infected with DNSChanger, you will lose access to the internet.
