Interview: How the DNSChanger malware works

Zafar Anjum | July 10, 2012
Many users have a chance of experiencing complete Internet outage if they remain unaware of this infection.

If users suspect that their system may have been compromised, they can use Norton Power Eraser, a free tool from Symantec to further analyse and remove any malware on their PCs.

Symantec customers can also refer to the following instructions (for the full details please visit here), applicable to all current and recent Symantec antivirus products, including the Symantec AntiVirus and Norton AntiVirus product lines:

                    i.            Disable System Restore.

                  ii.            Update the virus definitions.

                iii.            Run a full system scan.

                 iv.            Delete any values added to the registry.

                   v.            Delete the entries added to the RAS phonebook file.

In addition, for home users, Symantec offers a free public DNS service called Norton ConnectSafe that combines a reliable Web browsing experience with basic security features integrated. Users can activate Norton ConnectSafe by setting their DNS server addresses to the Norton DNS servers. For the full details, please visit here.

Eugene Teo is manager, security response, at Symantec.
