Disconnect the infected Systems from the network and download one of the tools from this site.

Downup Confiker Removal Tool

http://www.wissamidrissi.com/2009/03/downup-confiker-removal-tool-by.html

Download and install the Security Updates before reconnecting them to the network.

Security Update for Windows XP (KB958644)

Edit: to add a bit

You could also try this after running the tools in case anything else is lurking around. I have added a couple of scenerios with possable workarounds.

Follow the steps below with the System started and restarted in Safe Mode with Networking. Running in Safe Mode loads a minimal set of drivers for the Operating System. You can use these options to start Windows so that you can modify the registry or load or remove drivers. If you can access the Internet use it to download the files.

If you can't access the internet to update MBAM try the instructions below to clear a path to the internet to be able to run MBAM. You can also download the updates for MBAM and run them from the USB.

From another System download and install Spybot, update it and copy the the installed folders to a USB Stick. Copy MBAM and the Update as well.

Removing malware from System Restore points
To remove the malware, you must first disable System Restore, then scan the system with up-to-date antivirus software - allowing it to clean, delete, or quarantine any viruses found. After the system has been disinfected, you may then re-enable System Restore. The steps for disabling System Restore vary, depending on whether the default Start Menu or the Classic Start Menu is being used.

Default Start Menu XP
If using the default Start Menu, click Start | Control Panel | Performance and Maintenance | System. Select the System Restore tab and check "Turn off System Restore".

Classic Start Menu XP
If using the Classic Start Menu, click Start | Settings | Control Panel and double-click the System icon. Select the System Restore tab and check "Turn off System Restore".

Vista
Start, right mouse click Computer and select Properties. Select Advanced System Properties, click contine and then System Protection. Untick the box nect to Local Disk C: and click on Turn System Restore off.


After scanning the system and removing the offending malware, re-enable System Restore by repeating the steps, this time removing the check from "Turn off System Restore".

Once you have restarted the Infected System in Safe Mode, navigate to the USB stick and run Spybot.

Download Spybot - Search & Destroy and install it. Update it. http://www.safer-networking.org/en/download/index.html

Download Malwarebytes Anti-Malware, install it and update it.

<a href="http://download.bleepingcomputer.com/malwarebytes/mbam-setup.exe" target="_blank"><u>Malwarebytes</u></a>

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform Quick Scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.

If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
<a href="http://malwarebytes.gt500.org/mbam-rules.exe" target="_blank"><u>mbam-rules</u></a>

I would keep scanning with it until it is clean by closing out and rebooting and running it again.

Tip! If you want to write protect the USB drive/stick while you are working on an infected System.
In the recent release of Windows XP Service Pack 2 (SP2), a new feature was added by Microsoft to allow the write protection of USB block storage devices. This entails a simple Registry modification that requires no hardware devices to write protect thumb drives.

If the USB drive has no small switch for write protection you can turn it on through the Registry via Command Line.

REG ADD HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /v WriteProtect /t REG_DWORD /d 1 /f

and one to turn it off but a System restart is required. Place the Batch file on the USB to turn it off.

reg delete HKLM\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies /f


If TaskManager has been disabled this will enable TaskManager to allow access to the Registry.

Command line removal or create Batch files.

Click Start Run and type cmd and then press Enter.

Execute the following commands in the command line in order to activate the registry editor and Task Manager:

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableTaskMgr /f

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System /v DisableRegistryTools /f

With the new strains of Virus that have been created you may find it necessary to rename the executable files so that they will work. Rename mbam-setup.exe and then navigate to the install folder and rename mbam.exe. Do not change the files extension from .exe. Do the same with Spybot.


If you are still having problems try this.

Download Combofix and rename the executable Combofix.exe to cfix.exe before running it.

When all is clear you may need to tidy up the Registry.

Registry:

Download and install CCleaner to tidy up your Registry. Backup the Registry as you go along, rescan again and again saving as you go until there are no errors left.

Cleaner: Windows

When you first open Ccleaner you will have an option to Analyze or Run Cleaner, after checking the left Pane and making your choices. Delete all Temp Files. If you scroll down you will see a greyed out box that has Advanced next to it. Left click on it and keep pressing OK to all of the responses. I normally Untick Windows Log Files and Memory Dumps as they may come in handy.

You don't have to install all of the add ons or shortcuts just the one to the Desktop.
