Computer puts in a DNS address at every restart. Need help

This frigen computer has a DNS server address in the registry or something. Every time i turn it on, i have to go to the TCP/IPv4 and change it back to automatic. What a pain in the behind. I've been dealing with this for years. I had an online service fix it once and it worked fine for a long time. But i did that free upgrade to windows 10 and didn't like it, reverted back to my windows 7 and the dang thing came back. I have no idea what the tech did, but the whole time he was on the phone with me he kept saying this is very strange. I know he had to go into the registry and remove it though. That is well beyond my capability.

Welcome to the forum. What is the DNS that's set it may give us a clue what's going on. First thought is your infected changing DNS gives control over what you can do. The second possibility is your antivirus is doing it to monitor traffic

8*38*77*107

It's an MSI motherboard. I built this computer myself. The only other thing i've found on the internet about someone els having this issue was a dude with a visio computer. He posted that the problem was finally solved. It was his visio control center. I have an MSI control center on mine which came with the mother board. But i go into it and there is no kind of network settings. Something is telling it to go to this DNS server but i can't figure out what program is doing it. I go into TCP/IPv4 click advanced and there is nothing listed there, change it to automatic and i'm good. Restart or kill the computer, turn it back on and PRESTO ! it's back.......

The DNS is very fast DNS that blocks bad sites Cloud Delivered Enterprise Security by OpenDNS. Has instructions on how to set it up

Sadly that's a sign of virus problems. Google "8.38.77.107" and you'll find examples of others who have had the same issue. You should clean your system, note what you were infected with and email the abuse teams responsible for each IP to let them know a machine on their network was being used to log your internet traffic (abusenotice@cloudsouth.com and abuse@nl.leaseweb.com).

If it were my machine I'd reinstall the OS entirely, but if you want to try to rip it out by hand and hope you catch everything you can try online virus scanners or tools like hijackthis, superantispyware, malwarebytes etc.

As for why norton didn't catch it, that's hard to say exactly, but new viruses are put out all the time, and old ones are repackaged in clever ways so while eventually most antivirus programs will update to catch the most common attacks there will be times when you are vulnerable even with antivirus software running. Once your machine is compromised it can be hard for your antivirus to see what it needs to. For example, Norton can ask Windows for a list of every file on your computer so it can scan then, but because windows is now infected it can lie and never tell Norton about infected files on your machine. Norton won't catch anything but you are still infected.

AV software run from a live CD, bootable USB stick, or by mounting the hard drive on another computer (one set up just to clean virus infected drives) can catch those types of problems by not depending on the infected operating system for information about your hard drive and it's files, but unless you're dealing with virus issues all the time the investment in time and effort for those types of solutions aren't really worth it in most cases when a re-install will be faster.

A periodic reinstall can be a good thing anyway. You get the benefit of a clean system that runs like new and it forces you to review what you actually need installed etc. Just be sure to carefully back up your data and make sure you scan your backups for problems once your system is back up and your AV software reinstalled and updated.


Some additional advice: once you know what virus you have, you should research it a little to see how it spreads so you can avoid it in the future. Follow best practices when it comes to things like not opening attachments from strange emails, use an ad blocker in your web browser at all times and (if you can) disable java-script by default with something like noscript for firefox, also use anything other than adobe acrobat for 99% of the PDF files you view (the ones that don't involve forms for example). that should go a long way to help keep your system clean
