Since you cannot use your Internet, you are going to need access to another computer (family member, friend, etc) with an Internet connection. Download Malwarebytes Anti-Malware, save it to a flash (usb, pen, thumb, jump) drive or CD, transfer it to the infected machine, then install and run the program. If it does not run from the machine or you cannot transfer it, try running MBAM directly from the flash drive.
  • Double-click on Download_mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself.
  • Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply and exit MBAM.
Note: If MBAM encounters a file that is difficult to remove, you may be asked to reboot your computer so it can proceed with the disinfection process. Reagardless if prompted to restart the computer or not, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Please print out and follow the instructions for using SDFix in BC's self-help tutorial "How to use SDFix". This program is for Windows 2000/XP ONLY.
-- When using this tool, you must use the Administrator's account or an account with "Administrative rights"
-- Disconnect from the Internet and temporarily disable your anti-virus and any anti-malware real time protection before performing a scan.

When done, the SDFix report log will open in notepad and automatically be saved in the SDFix folder as Report.txt. Please copy and paste the contents of Report.txt in your next reply. Be sure to renable you anti-virus and and other security programs before connecting to the Internet.

Please open the SDFix folder or download XP_CodecRepair.inf and save it to your desktop. <- for Windows XP ONLY.
  • Right-click on XP_CodecRepair.inf and select Install from the Context menu.
  • Note: To download the .inf file, go to File, choose "Save page as" All Files and save XP_CodecRepair.inf to your desktop.
  • Then log off or reboot to apply the changes.

After rebooting into safe mode, when you are at the logon prompt, make sure you log in as the same user account which you used to download SDFix. If not, you may not be able to find the file on your desktop. If your still having problems finding it, go back to normal mode and move it to the root of the system drive (usually C:\) where you will be able to easily locate it when going into safe mode. Then move it from there to the desktop and follow the rest of the instructions.

You're welcome.

Tips to protect yourself against malware and reduce the potential for re-infection, be sure to read:
• "Simple and easy ways to keep your computer safe".
• "How did I get infected?, With steps so it does not happen again!".
• "Best Practices - Internet Safety for 2008".
• "Hardening Windows Security - Part 1 & Part 2".
• "IE Recommended Minimal Security Settings" - "How to Secure Your Web Browser".

• Avoid online gaming sites and peer-to-peer (P2P) or file sharing programs as they are a security risk which can make your system susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans target and spread across P2P files sharing networks and gaming sites. In some instances the infection may cause so much damage to your system that recovery is not possible and the only option is to wipe your drive, reformat and reinstall the OS. The best way to reduce the risk of infection is to avoid gaming sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.
