BBC News: Early in the morning Monday, July 9, the FBI shut down the temporary servers it set up to assist victims of the DNS Changer malware. That move prevented systems affected with the virus from accessing the Internet as usual, but so far, the impact of the shut-down has been "minimal" say security experts. At its height, DNS Changer affected more than 4 million systems, but over time, most of those systems have been cleaned, leaving only 300,000 systems still infected. In the U.S., 69,517 systems still have the virus, but experts believe that many of the infected devices are not actively used or maintained.
Many ISPs have put into place solutions designed to help victims who experience problems related to DNS Changer.
