Situation: Windows 7 Professional 64bit SP1 with all of the current patches. Wireless N connection TCP/IP 4 DNS server is set to 127.0.0.1. I did not do this

Option to obtain DNS server automatically is disabled. Any changes made through any means attempted revert to 127.0.0.1 on close.

I have run multiple antivirus scanners (MSE, AGV...) and other tools (MalewareBytes, Combofix) and they have found nothing.

Deleted the wireless card from Device Manager and reinstalled drivers: obtain DNS server automatically is no longer disabled, but as with any other setting, it reverts to static 127.0.0.1 on close.

Reset TCP/IP stack. No change. This sort of thing makes me very unhappy. This system was the victim of an exploit that attempted to allow remote execution that was identified and stopped, but I am thinking that I was not as lucky as I had believed myself to be at the time.

Any ideas

It sounds like that recent DNS Hijack Virus. Is there any reason why don't think it's that?

Just looked at the link and I would tend to think that is not the problem since DNS server address in netmarcos case is 127.0.0.1 rather than those of the servers set up by the hackers and then the FBI. Right?

Update: While I am still not sure what initiated this problem, it has been resolved. Reinstalling drivers and such finally fixed it. I wish I knew what had caused it, but it is gone now and I am sure that I will never find out.
