As a result of a criminal infrastructure called ‘Operation GhostClick’, which was set up to divert advertising revenues from legitimate sites, Public Safety Canada has set up this easy system check tool to detect the ‘DNSChanger Malware’ and let you know if your system is affected. It is estimated that those who remain affected in Canada number over 9,000 and over 270,000 in the United States.
Infected systems lose all internet connectivity on Monday, July 9, 2012 as that is the day the authorities have set to close down the interim connectivity to ensure ad revenues are not directed illegally.
Once this is shut down, any systems affected will lose all connectivity and must go through a cleaning procedure. Any infected computer owners can access this link for further information, regardless of location. Follow the recommendations and procedures to clean your system.
I would recommend the preemptive action of visiting this link, which will flag with a red banner across the top and bottom of the page if your computer is infected. If the banners are green, you have nothing to worry about.
