CAUTION - Please DO NOT USE any SPECIALIZED MALWARE REMOVAL TOOLS such as Combofix, without supervision.

Be advised that running specialized tools on your own, is done solely at your own risk. Doing so could make your pc inoperable and could require a full reinstall of your OS, losing all your programs and data.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

PREPARING FOR THE MALWARE REMOVAL PROCESS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


We suggest you print out these instructions

Vista and Windows 7 users:
1.These tools MUST be run from the executable. (.exe) every time you run them
2. With Admin Rights > Right click, choose "Run as Administrator"

NOTE: If you are unable to complete any of these steps for any reason, please move on to the next step and advise in your post which step(s) you could not complete.

~~~~~
FIRST
~~~~~

Create a new system restore point

Posted Image System Restore (Windows Vista, XP and ME)
Why? This ensures there's a valid system restore point, in case it's needed. We use a simple program called SysRestorePoint that automates the steps of creating a restore point.
  • Create a New System Restore Point:
  • Download SysRestorePoint to your desktop, or other location.
  • Double click SysRestorePoint.exe to create a new system restore point.
  • A box will pop up as it's creating the restore point, and provide notification when complete. When finished, close that window and exit the program.

Backup your Registry

Posted Image ERUNT - Download - Homepage
Why? This ensures we have a valid registry backup. ERUNT (Emergency Recovery Utility NT) allows you to store a complete backup of your registry and restore if needed. Removing modern malware infections often requires making changes to the registry, and a corrupt registry can prevent a system from booting. Compatible with Windows NT, 2000, 2003, XP, Vista, 32 & 64-bit versions.

  • Download ERUNT
  • Double-click erunt_setup.exe to run.
  • Follow the prompts and install using the default configuration (setup language, install location, shortcuts...).
  • Say No to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later.
    Posted Image
  • Start ERUNT
  • Choose a location for the backup
    The default location C:\WINDOWS\ERDNT\[today's date] is preferred
    Posted Image
  • The first two check boxes are ticked by default (System registry and Current user registry).
  • Press OK
  • When prompted, click YES to create a new folder.
  • Progress bars will show backup status.
  • A confirmation window will popup when complete. Click OK to close.

CD EMULATION SOFTWARE

Do not re-enable these drivers until otherwise instructed.


NOTE:

You must remember to re-enable your Emulation drivers once we are finished, double click DeFogger to run the tool.
  • The application window will appear
  • Click the Re-enable button to re-enable your CD Emulation drivers

Malware and Spyware Removal Forum Rules:
  • Combofix should NEVER be run unless requested. While it's a powerful tool useful for removing a number of infections, things can, and do go wrong. Sometimes systems even refuse to boot. There are safeguards built into Combofix, but only someone trained in its use will be able to help you recover. The logs generated can also be very difficult to interpret properly.
  • Please stay with your original topic when posting follow ups.Use the ADD REPLY button, do not "QUOTE" the previous post.
  • The "Topic Title" should contain the name of the infection that you are having a problem with e.g. WinTools, http://...sp.html etc. Use the "Topic Description" to include more details. This will help you get faster responses as some people are more familiar with certain infections.
  • Tell us if you're having any problems, and please be specific. Let us know what you've already done to fix it (if anything).
  • If you do not understand a step, do not panic, simply ask for direction and information. We will offer any advice necessary to help you.
  • Please only post your topic once. Duplicate posts will be closed, it just creates additional work for the staff members trying to help you.
  • Do not create posts at multiple forums. Logs take time to diagnose, and doing this will waste multiple helpers time which is already over-stretched. If you do this your topic will be closed.
  • Do not attach logs unless directed to do so, as it is harder to read that way. Post them instead
  • If you are being helped and you haven't replied within 3 days your topic will be closed as inactive.
    If that is the case, please start a new topic when you have the time needed to finish all the instructions.
