How to find Whether you PC is Infected by DNSChanger malware ?


DNSChanger malware scam!!


In 2007 small group of cyber criminals distributed a malware called ‘DNSChanger’ which when installed would change the user's DNS settings to point to the criminals rogue DNS network. It redirects valid searches and URLs to malicious Web sites, attempt to steal personal information and generate illegal Ad revenue to criminals.

To combat this, FBI launched mission called ‘Operation Ghost Click’ which resulted in number of arrests. FBI provided list of infected servers to Internet Service Providers, and instead of shutting down the same they redirected infected servers to healthy DNS Servers. In January of this year, the German Federal Office for Information Security announced that the tamed DNS network would be shut down on March 8; however, it appears that the efforts to clear the DNS changer malware from the millions of infected PCs has taken a lot longer than expected with hundreds of thousands still being infected, according to the DNS Changer Working Group. Therefore, the closure of the rogue DNS network has been delayed for four months, and is now scheduled to be shut down on July 9, 2012. . This action means that many of the millions of computers that are still currently infected with the DNSChanger malware should now be receiving healthy DNS server activity even if the DNS server IP addresses on their systems are changed by the malware until July 9. If still malware is not removed then it might stop working after Due date.
