DNS server address keeps changing back automatically

Hello,
I am having problems with my lan connection, somehow my DNS server addresses have changed to something else and i am having trouble entering some websites, email etc.

I have entered the tcp/ip properties and set the DNS to obtain automatically. I click ok and close the connection properties window. I open the properties window again immediately after closing it and the DNS is as it was before I changed it.

I have also tried entering it manually but it still changes back.
I have tried restarting in safemode and changing from there but still the problem persists.
I have reset the winsocks but still to no avail.

Any help would be greatly appreciated,

thanks in advance,

pythonv.

Does it change to a known dns server ip or a strange one?
Do you get any errors when hitting OK button?

I don't get any errors, and the dns server ip i get is some company in the Ukraine. that is quite strange.

Thanks for the speedy response.

I have never experienced this myself, but it sounds like something did hijack you dns setup.
If it is a trojan or a virus that does that i recommend reinstall of windows. They can hide everywhere and wake up later sometime in the future - even if scanners find some infetcted files and remove them.

Do you think there may be any other solution to this problem, i'm not very keen on reinstalling windows.

And if I do reinstall windows, do you think my files would be compromised with some virus, trojan or whatever. I would prefer to keep some of my files.

You could try running some scanners to see if it helps. Try running Spybot S&D and Malwarebyte's Anti-malware in safe mode.

I am running a check using the Spybot S&D, it has found a DNSChanger trojan. I shall delete it when the scan ends.

Thanks for your help, it is very much appreciated.
