Re: Help Removing Zlob.DNSChanger.rtk

That's strange. The link to the ComboFix guide works for me. Where abouts did it break down for you?



Lets continue on with your fix.


Open HijackThis and click on 'Do a System Scan Only'. Check the following entries (If they still exist, make sure you do not miss any)

O17 - HKLM\System\CS2\Services\Tcpip\..\{4ADACCDD-62B5-449D-B840-AC994C684D6F}: NameServer = 85.255.112.11;85.255.112.93

Please remember to close all other windows, including browsers then click Fix checked.

--------------------------------------------------------------

Go to Start->Run and type in regedit and hit OK. Go to File->Export and save the registry somewhere as a backup. Close the Registry Editor now.

Open notepad and copy/paste the text in the quotebox below:
(don't forget to copy and paste REGEDIT4)

Quote:
REGEDIT4

[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\{bed46197-a540-11dd-a4a8-0017315276a8}]

[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\I]

[-HKEY_CURRENT_USER\software\microsoft\windows\currentversion\explorer\mountpoints2\C]
Save the file as "delete.reg". Make sure to save it with the quotes. Choose to "Save type as - All Files"
It should look like this:

Double click on the delete.reg file and choose Yes to merge/add it to the registry. You may delete the file afterwards.

--------------------------------------------------------------

Establish an internet connection & perform an online scan with Internet Explorer at Kaspersky Online Scanner

Answer Yes, when prompted to install an ActiveX component.
  • The program will then begin downloading the latest definition files.
  • Once the files have been downloaded click on NEXT
  • Locate the Scan Settings button & configure to:
    • Scan using the following Anti-Virus database:
      • Extended
    • Scan Options:
      • Scan Archives
      • Scan Mail Bases
  • Click OK & have it scan My Computer
  • Once the scan is complete, it will display if your system has been infected. It does not provide an option to clean/disinfect. We only require a report from it.





  • Click the Save as Text button to save the file to your desktop so that you may post it in your next reply
* Turn off the real time scanner of any existing antivirus program while performing the online scan

--------------------------------------------------------------

Please run HiJackThis again and post the resulting log.

Also, please update me on how your system is behaving
