Exactly the same. I had to re-read it and then I got that "PG" wasn't PG (Paul).

I suggest you contact the CSIS and ask them directly why they've backdoored your computer.

If your domain registrar is showing the right name server then it should be okay. Try to contact the registrar and talk to them about the problem, They should be able to fix it. It may also take some time for the DNS to set (aprox. 24 Hours).

Thanks. The registrar has not been very helpful. We waited 48 hours and still no resolution.

Hmmm... I highly doubt your site has been hijacked if you can still access the registrar and your whois information is showing. Can you tell me the name of the domain and registrar. Thanks

It is for a client who is not comfortable publicly sharing the name of the domain. Is there anything I can do besides waiting it out?

If that's the case then what I suggest is that you try to contact the registrar as this seems to be a mistake on their part.
