(Yet another) DNSUnlocker infection

[Jacy Ribeiro]

Besides everything that I've written before, I would like you to know that I have previously included this section:

==================== Internet (Whitelisted) ====================

(If an item is included in the fixlist, if it is a registry item it will be removed or restored to default.)

Tcpip\..\Interfaces\{0c97f166-b080-4b68-a871-dec4aa63526f}: [DhcpNameServer] 192.168.43.1
Tcpip\..\Interfaces\{b3e02eb9-2d5e-4c55-99d3-e9f43ef40a12}: [NameServer] 199.203.131.145,82.163.143.167
Tcpip\..\Interfaces\{bde452b2-d85d-43aa-b597-b7e8554f50a1}: [NameServer] 199.203.131.145,82.163.143.167


Among those that I've tried to fix, but adding it resulted in no internet connection whatsoever, forcing me to revert the changes using the windows restoration tool.

Hello,



They call me TwinHeadedEagle around here, and I'll be working with you.



Before we start please read and note the following:

• At the top of your post, please click on the "Watch thread" button and make sure to check Watch this thread...and receive email notifications. This will send an email to you as soon as I reply to your topic, allowing me to solve your problem faster.
• Please do not install any new software during the cleaning process other than the tools I provide for you. This can hinder the cleaning process. Please do not perform System Restore or any other restore.
• Instructions I give to you are very simple and made for complete beginner to follow. That's why you need to read through my instructions carefully and completely before executing them.
• Please do not run any tools other than the ones I ask you to, when I ask you to. Some of these tools can be very dangerous if used improperly. Also, if you use a tool that I have not requested you use, it can cause false positives, thereby delaying the complete cleaning of your machine.
  
• All tools we use here are completely clean and do not contain any malware. If your antivirus detects them as malicious, please disable your antivirus and then continue.
• If during the process you run across anything that is not in my instructions, please stop and ask. If any tool is running too much time (few hours), please stop and inform me.
• I visit forum several times at day, making sure to respond to everyone's topic as fast as possible. But bear in mind that I have private life like everyone and I cannot be here 24/7. So please be patient with me. Also, some infections require less, and some more time to be removed completely, so bear this in mind and be patient.
• Please stay with me until the end of all steps and procedures and I declare your system clean. Just because there is a lack of symptoms does not indicate a clean machine. If you solved your problem yourself, set aside two minutes to let me know.
  
• Please attach all report using
  
  button below. Doing this, you make it easier for me to analyze and fix your problem.
  
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay for the repair.

Howdy mate,

As I said, fixing these lines ultimately result in me without internet connection as I am now, posting from my phone.

Let me add something that might help, how my internet work:

I'm at the end of the world in a joke of a city on my home state in Brazil, I work here and go back to the civilization on weekends.

The only "isp" here is a guy who brought an optical fiber from a more civilized town and I suspect that he works as a hub to sell a share of this connection to his clients. I suspect this cos I can see other people's machines on the "network" section of windows explorer.

That said, I think those dhcp servers are part of the config of this integrated network that we're in.

What would you sugest? I can call the guy and tell him to come "fix" the internet to see what he does, I wasn't home the first time he configured it.

Let's try this:

Check Disk

• Press the
  
  + R on your keyboard at the same time. Type cmd and click OK.
• Copy/Enter the command below and press Enter:

• ipconfig /registerdns

Reboot your PC and let me know how is the situation now?

Same thing, no internet after reboot, though the command was deemed successful by the prompt message.

I talked to the "ISP" guy who confirmed that these configurations were made by him on the TCP/IPv4 protocol of the private network I'm at.

So I reverted the changes to have internet again, making the configurations that he told me.

What now?

 

[TwinHeadedEagle]

How is your PC behaving now?

 

[Jacy Ribeiro]

Same thing.

It is important to notice that when I was infected the hiperlinks and pop ups were everywhere. After I did some cleaning up it is restricted to what it is now: some hiperlinks, no pop ups but some web publicity is replaced by DNSUnlocker links.

It must be something really small that needs cleaning for this bug to die.

 

[TwinHeadedEagle]

Does it happen in all browsers?

 

[Jacy Ribeiro]

It was. Since one of the suspicious things was the "chrome developer version" thing, I uninstalled both chrome and firefox and was using only the Edge (the new browser that comes in win 10) and also tried on the usual IE to see if anything had changed, but nope, even after I did the "browser full reset" that some sites recommend.

I've installed chrome and firefox after your question and DNSUnlocker appear on both.
