No internet after clearing virus with mwbt


Recommended Posts



I am new to this forum. I ran MWBT to clear DNS unblocker. Staright after that I was unable to load any web pages in any browser. my connection says "limited". I am using a wireless router on a home network. I also tried hot spotting my phone which normally works but had the same problem. I do have one connection that does not seem to be affected which is a dongle that attaches to the laptop. Is MWBT affecting the internet or do I have still have the virus? Help please. Thx

Can you attach the MalwareBytes Anti-Malware log that shows the infection(s) removed?


Download the attached fixlist.txt file and save it to the Desktop.  Fixlist.txt

NOTE. It's important that both files, FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system

Run FRST64 by right clicking on the FRST64.exe file, selecting "Run as Administrator..".  The User Account Control may open up; if it does, select Yes to continue to let FRST open and load.  

The tool will check for an updated version of itself every time it loads; please allow it to do this and the program will either inform you it is downloading an updated copy (and to wait until it is safe to continue) or show that it is ready to use (meaning there is no update found) and you can continue on.  Press the Fix button just once and wait.  The tool will create a restore point, process the script and ask for a restart of your system.


If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.

When finished FRST will generate a log on the Desktop (Fixlog.txt). Please post the log in your next reply.

How is the system running now?  Can you connect to the network now?

I did as requested. I had to restart the netadaptor repair program after the reboot (cause nothing happened) and then reticked the options after the one requiring reboot and then hit run again - was that right?? I have attached the logs. I was also asked whether to repair just the wi fi network adaptor or all adaptors and I said wi fi only. Hope this is OK.

It is a samsung laptop. I had already tried the F12 thing but still got the same message. No networks are showing up. When I click on the network icon at bottom of windows 8 I get three options - 1. View network settings, 2. No connections are available and 3. Troubleshoot. I tried troubleshoot and it tells me I need to connect an ethernet cable. I used to click the network icon and it would search for networks but it doesn't do that now.

Right click on the Network icon and select Open Network and Sharing center. 

Click on Change Adapter settings. 

Select the Wi-Fi connection and right click on it.

Select Properties.

This opens the Wi-Fi properties window.  In the middle is a box showing "This connection uses the following items:".  Can you take some screenshots of that list (you may have to make more than one screenshot to capture the entire list) and post them here?

Thank you for the images. 


Have you tried turning the router off, waiting 30 secs (or longer) and turning it back on?


By the way, the USB dongle you are using is a Broadband based connection.  It is wireless but is using a cell phone type connection to get to the internet.  I don't believe it is going through your router.

I have other computers in the house that are working on the network fine. Also, I have been at work today with the computer and it was not registering the work network either. Any ideas of what else I can do or do I need to get it to a computer tech?? Could the repair process have affected the drivers or do you have a theory on what may have happened? Thanks heaps.

I checked the logs so far; let's get one more look for nasties and go from there ....

AdwCleaner by Xplode

Download AdwCleaner from here or from here. Save the file to the desktop.

NOTE: If you are using IE 8 or above you may get a warning that stops the program from downloading. Just click on the warning and allow the download to complete.

Close all open windows and browsers.

  • Vista/7/8 users: Right click the AdwCleaner icon on the desktop, click Run as administrator and accept the UAC prompt to run AdwCleaner.

    You will see the following console:


  • Click the Scan button and wait for the scan to finish.
  • After the Scan has finished the window may or may not show what it found and above, in the progress bar, you will see: Pending. Please uncheck elements you don't want to remove.
  • Click the Clean button.
  • Everything checked will be deleted.
  • When the program has finished cleaning a report appears.
  • Once done it may ask to reboot (depending on what it found to remove): please allow this


  • On reboot a log will be produced please copy / paste that in your next reply. This report is also saved to C:\AdwCleaner\AdwCleaner[s0].txt

NOTE: If you see AVG Secure Search being targeted for deletion, Here's Why and Here. You can always Reinstall it.
