all of the posts in that link. If you did try running sfc /scannow and have your XP CD ready.
If that fails try this.
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.
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".
Click Start, Run type msconfig and press Enter.
Now if you have the Configuration Utility open.
Configure selective startup options
In the System Configuration Utility dialog box, click the General tab, and then click Selective Startup.
Click to clear the Process SYSTEM.INI File check box.
Click to clear the Process WIN.INI File check box.
Click to clear the Load Startup Items check box. Verify that Load System Services and Use Original BOOT.INI are checked.
Click the Services tab.
Click to select the Hide All Microsoft Services check box.
Click Disable All, and then click OK.
When you are prompted, save the settings and restart the PC.
When the System is disinfected re-run the Configuration Utility and in the System Configuration Utility dialog box, click the General tab, and then click Normal Startup.
Download Malwarebytes Anti-Malware, install it and update it.
Malwarebytes
* 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.

* 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.
mbam-rules
I would keep scanning with it until it is clean by closing out and rebooting and running it again.
From another PC download and install Spybot, update it and copy the the installed folders to a USB Stick.
Restart the PC 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
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.

How to check the Host file
Step 1: Click the Start button and select Run. Now type the following text in that Run box and press Enter:
notepad c:\WINDOWS\system32\drivers\etc\hosts
Step 2: You will see a new notepad window on your screen containing some information. You should have a single entry of 127.0.0.1 localhost. If there are any other entries in there it means that those sites are being blocked and it is probably due to an infection. Unless you made the extra entries delete them all but 127.0.0.1 localhost.
If it is the DNS changer fixwareout will remove this.
Fixwareout
The DNSChanger trojan is usually a small file (about 1.5 kilobytes) that is designed to change the 'NameServer' Registry key value to a custom IP address. This IP address is usually encrypted in the body of a trojan. As a result of this change a victim's computer will contact the newly assigned DNS server to resolve names of different webservers. And some of the resolved names will not point to legitimate websites - they will point to fake websites that look like real ones, but are created to steal sensitive information (like credit card numbers, logins and passwords).
VARIANT: Trojan.Win32.DNSChanger.al
Update your Antivirus software.
If TaskManager has been disabled this will enable TaskManager to allow access to the Registry.

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