So first of all what is DNS virus, for example, what is DNS Unlocker? DNS Unlocker is used to redirect user to the specific DNS-servers where whole traffic what users will get infected with a different type of viruses, adware, malware and so on. Such virus easily hides every movement of the user’s eye, so many victims didn’t even know that their computer infected with DNS-type virus and just trying to remove adware what was installed after a dirty trick of DNS Unlocker.

Why we choose DNS Unlocker to describe whole DNS type virus? Well, because this virus has unique technique what allow this virus change network settings, so users don’t even suspect a thing. It changes network adapter via this path HKLM\SYSTEM\CURRENTCONTROLSET\SERVICES\TCPIP\PARAMETERS. The user won’t see that his network setting changed even if he check it by himself. After this virus change network setting user won’t see it (especially if user use “Obtain DNS server address automatically”).
DNS Unlocker used static DNS address what won’t be displayed in the list when user check local setting manually. ipconfig / all command also specifies the use of DHCP, but it displays a statically defined DNS address. It’s really hard to find out for what network connection is using DHCP and for what connection uses static addresses. So often user just closes command line and keep on searching for the solution.
The worst in this situation is that the developers of DNS Unlocker and alike viruses know that the average user can’t check the network setting alone, so this weak spot is used by unwanted applications to redirect user requests to the DNS they need. It’s used as a DNS hijack method and forces the user to work with spoofed DNS-servers.
