DNS Changer cannot get rid of it

You had signs of a DNS hijacker infection that has mostly been removed. The infection you have is known to infect router hardware. If you have a router hooked up then you need to follow the instructions for your hardware and reset it to factory default settings. Normally there is a recessed push button type switch that needs to be held down for some number of seconds to do this. After resetting to factory defaults on your router, you will need to reconfigure the router for your network if you have made any changes to the default network setup. After doing this, continue with on with the below.


Download HostsXpert and then follow the below steps.

* Unzip HostsXpert.zip
* It will create a folder named HostsXpert in whatever folder you extract it to.
* Run HostsXpert.exe by double clicking on it.
* Click the Make Writeable? button. (if you only see a Make Read-Only selection, it is already writeable so skip this button).
* Click Restore Microsoft's Hosts File and then click OK.
* Click the X to exit the program

Now:
Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Run C:\MGtools\analyse.exe by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator). This is really HijackThis (select Do a system scan only) and select the following lines but DO NOT CLICK FIX until you exit all browser sessions including the one you are reading in right now:

After clicking Fix, exit HJT.

* Make sure that combofix.exe that you downloaded while doing the READ & RUN ME is on your Desktop but Do not run it!
If it is not on your Desktop, the below will not work.
* Also make sure you have shut down all protection software (antivirus, antispyware...etc) or they may get in the way of allowing ComboFix to run properly.
* If ComboFix tells you it needs to update to a new version, make sure you allow it to update.
* Open Notepad and copy/paste the text in the below code box into it (make sure you scroll all the way down in the code box to get all lines selected ):

Code:

* Save the above as CFscript.txt and make sure you save it to the same location (should be on your Desktop) as ComboFix.exe
* At this point, you MUST EXIT ALL BROWSERS NOW before continuing!
* You should have both the ComboFix.exe and CFScript.txt icons on your Desktop.
If it asks you to overide the prvevious file with the same name, click YES.
* Now use your mouse to drag CFscript.txt on top of ComboFix.exe
http://img.photobucket.com/albums/v666/sUBs/CFScriptB-4.gif
* Follow the prompts.
* When it finishes, a log will be produced named c:\combofix.txt
* I will ask for this log below

Note:

Do not mouseclick combofix's window while it is running. That may cause it to stall.

Now run the C:\MGtools\GetLogs.bat file by double clicking on it (Note: if using Vista, don't double click, use right click and select Run As Administrator).

Then attach the below logs:

* C:\ComboFix.txt
* C:\MGlogs.zip

Make sure you tell me how things are working now!

 

Yes.

 

If you reset your router and then do my fix while keeping the computer disconnected from the router, you will be fine. After the fix, reconnect and attach the requested logs.

 

Please disable all anti-virus and anti-spyware programs while we do the following (re-enable when you are finished):

Now copy just the bold text below to notepad (Do not include any space above the word REGEDIT). Save it as fixME.reg to your desktop. Be sure the "Save as" type is set to "all files" Once you have saved it double click it and allow it to merge with the registry.

Make sure that you tell me if you receive a success message about adding the above
to the registry. If you do not get a success message, it definitely did not work.

Let me know it that works. You may need to go into your LAN configuration and check your settings.

 

Did you ever reset your router back to factory defaults? If not, you need to do this since DNS changer infections can change the router. It would even be a good idea after the reset, to look for any available router firmware update and install it.

You should also supply a new log from MGtools for Tim to look at afterwards.

 

Esp. since your MBAM log indicates that you didnt allow it to fix what it found!! So please attach a log showing that MBAM fixed those issues as well as the new MGLogs.zip.

 

Although the HJT log you attached is clean, I wanted a new MGLogs.zip.
