No DNS after Virus

Experts -

I've been struggling with a virus infected PC here at my shop. I believe i successfully removed the virus but now the DNS will not work.

A little background -
Internet was working fine before, but once i removed the virus, hitman had removed AFD, so dhcp was not working. After replacing AFD with a working file, DHCP was now working. From then though, DNS will not work. I can ping external IPS such as 8.8.8.8, but not google.com

I have tried many things -
More virus Scans - Hitman Pro, Combofix, Malwarebytes, Kaspersky
Ran Winsock Fix
Reset the TCP/IP
Install SP3 overtop of SP3
Ensured Firewalls Are Off
Checked Hosts file, it is clean
Checked Proxy - None

I'm trying not to repair install or format just because i've already spent some time fixing this up and i feel i am very close, any ideas on what to try next?

No Love still, i tried system restore, that just undid my AFD work so DHCP is broken again, i'm reverting back now... I might try a repair install, but that always jacks stuff up.

Please try running all of the Menu Options in "RogueKiller". It automates a lot of the repairs that many of us do manually:
