Thousands of Internet users worldwide could lose access to websites, email, chat and social networking tomorrow after the FBI shuts down temporary servers that were used to replace fraudulent servers operated by hackers.
This blackout will affect all systems infected with the DNSChanger Trojan, a malware program created to redirect the Internet traffic of unsuspecting consumers to websites from which these cybercriminals could profit.
Most users who are affected by the trojan should have long ago been alerted by their Internet Service Providers that they need to correct their DNS settings and remove the rootkit infection that is responsible.
McAfee announced the release of free tools to help consumers check to see if their computers have been infected by the Trojan, and to help them modify and restore their Internet settings if they test positive. Consumers can simply visit www.mcafee.com/dnscheck and click a button to run a check. Take a look at this blog post from Robert Siciliano, Online Security and Safety Evangelist to McAfee, for more information:
