Please note that the forum is very busy and if I don't hear from you within three days this thread will be closed.

Please copy this page to Notepad and Save it to your Desktop in order to assist you when carrying out the following instructions.

Before beginning the fix, read this post completely. If there's anything that you do not understand, kindly ask your questions before proceeding.
Ensure that there aren't any opened browsers when you are carrying out the procedures below.

It is IMPORTANT that you don't miss a step & perform everything in the correct order/sequence.

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

Please note that these fixes are not instantaneous. Most infections require more than one round to properly eradicate.

Please stay with me until given the 'all clear' even if symptoms seemingly abate.

Kindly follow my instructions and please do no fixing on your own or running of scanners unless requested by a helper.


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

Download ComboFix and the Microsoft file to a USB drive on another computer and transfer the files to your desktop.

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

Please download ComboFix and Save it to your Desktop.

**Note: It is important that it is saved directly to your desktop**

First, we need to install the Windows Recovery Console.

The Windows Recovery Console will allow you to boot up into a special recovery(repair) mode, if needed. This allows us to help you in the case that your computer has a problem after an attempted removal of malware. It is a simple procedure that will only take a few moments of your time.

Download the file from this Microsoft page:

http://www.microsoft.com/downloads/d...displaylang=en

Do not be concerned that this file is for SP2 and you have SP3. It will work just fine on your system.

Save it as it is originally named to your Desktop.

Now close all open windows and programs, including all antivirus and antispyware programs, usually via a right-click on the System Tray icon.



Then drag the setup package onto ComboFix.exe and drop it. Follow the prompts to start ComboFix and when prompted, agree to the End-User License Agreement to install the Recovery Console.

As part of installing the Recovery Console, ComboFix will begin to run. Your desktop may disappear. This is normal. It will return.

ComboFix will now automatically install the Windows Recovery Console onto your computer, which will show up as a new option when booting up your computer. Do not select the Windows Recovery Console option when you start your computer unless requested to by a helper.

Once the Recovery Console is installed, this blue window will appear:



Please continue as follows:
  • Close/disable all antivirus and antispyware programs, usually via a right-click on the System Tray icon, so they do not interfere with the running of ComboFix.
  • Please click Yes to continue scanning for malware.
When the tool is finished, it will produce a log for you.

Please post that log, ComboFix.txt, in your next reply.

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

Download Flash_Disinfector.exe and Save it to your Desktop.
  • Close any open browsers.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives including your mobile phone. Please do so and allow the utility to clean up all those drives.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
