Hello,

 

So one day my friend and I tried to open Mozilla Firefox, and once we did the page wouldn't open and showed the error: DNS_Probe_Finished_NXDomain

 

When trying on different browsing programs, the same error would appear. We tried changing the DNS servers, but the same problems continued. 

We're thinking it is a possible virus and tried to install the Antimalware program,Malware Bytes, however, something is stopping it from fully installing. 

 

We've read through some of the forums where the error occurs, but we're worried about making mistakes that could make the situation even worse.

 

What are possible steps we could take to fix this problem?

 

It is a Toshiba Satellite C55T Series with Windows 8.1

 

Thank you for your help and I hope you get to us soon.

Hello,

 

I'm not sure how to explain the problem as clearly as I have before, but to explain again, We're experiencing the DNS_Probe_Finished_NXDomain error when opening the internet browsers (Chrome and Mozilla Firefox) and now all programs (steam, origin, and others) are disconnected from the internet as well. We attempted to install Malware Bytes, but we keep getting a dialogue box saying that it can't install. Because of this, we're assuming it's a virus.

 

The computer is a Toshiba Satellite C55T Series with Windows 8.1

 

Thank you for your help

To see what's under the hood it is imperative that you run a scan of your computer and post the logs in your next reply.

I know you've been waiting a while now, but I must inform you that it will take me a day or so to review those logs.

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system, download both of them and try to run them. Only one of them will run on your system, that will be the right version.
  • Right-click FRST then click "Run as administrator" (XP users: click run after receipt of Windows Security Warning - Open File).
  • When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • When finished, it will produce a log called FRST.txt in the same directory the tool was run from.
  • Please copy and paste the log in your next reply.
Note 2: The first time the tool is run it generates another log (Addition.txt - also located in the same directory the tool was run from). Please also paste that, along with the FRST.txt into your next reply.

Please download MiniToolBox, save it to your desktop and run it.
Checkmark the following checkboxes:
  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices
  • List Users, Partitions and Memory size.
  • List Minidump Files
  • List Restore Points
Click Go and post the result (MTB.txt). A copy of MTB.txt will be saved in the same directory the tool is run.
