The one in particular are these mentioned:
Firstly, the DNS settings on the router has been changed to be that of the "virus". So just select "restore defaults" on the router (Or input some other DNS server yourself, I use OpenDNS!), and change the username/password.
Secondly, the DNS settings on the host PC have been changed, and an application is still lurking changing it back. A simple virus scan in Windows Safe-Mode gets rid of it, I use Avira-AntiVir Pro.
Very simple solution, and it would be appreciated if one of the staff would put this information in the 2 BleepingComputer topics above.
