Hello and welcome..
run MBAM:
Please download Malwarebytes Anti-Malware (v1.36) and save it to your desktop.
alternate download link 1
alternate download link 2
If you have a previous version of MBAM, remove it via Add/Remove Programs and download a fresh copy.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install. Alternatively, you can update through MBAM's interface from a clean computer, copy the definitions (rules.ref) located in C:\Documents and Settings\All Users\Application Data\Malwarebytes\Malwarebytes' Anti-Malware from that system to a usb stick or CD and then copy it to the infected machine.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Regardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you after scanning with MBAM. Please temporarily disable such programs or permit them to allow the changes.

I have installed MBAM, but the application is not opening. I guess the trojan isn't letting the MBAM start.

try renaming the .exe of MBAM to something else.
You can find the .exe here (unless you saved it elsewhere):
%root%\Program Files\Malwarebytes' Anti-Malware\
Its the one that is just "mbam"
Change the name to whatever you like and try running it again.

Althought the MBAM says it has successfully deleted it, but my ESET SMART SECURITY 4, shows it still sitting in my computer memory.

OK try again.. Before running MBAM. disconnect fro the internet.

Now we work on the DNS changer,,,,
Next you must reset the router to its default configuration. This can be done by inserting something tiny like a paper clip end or pencil tip into a small hole labeled "reset" located on the back of the router. Press and hold down the small button inside until the lights on the front of the router blink off and then on again (usually about 10 seconds). If you donít know the router's default password, you can look it up HERE.

However, if there are other Zlob-infected machines using the same router, they will need to be cleared with the above steps before resetting the router. Otherwise, the malware will simply go back and change the router's DNS settings. You also need to reconfigure any security settings you had in place prior to the reset. Check out this site HERE for video tutorials on how to properly configure your router's encryption and security settings. You may also need to consult with your Internet service provider to find out which DNS servers your network should be using.

Once you have ran Malwarebytes' Anti-Malware on the infected system, and reset the router to its default configuration you can reconnect to the internet, and router.

Is ESET still seeing it now?
