I see a lack of Windows updates and no Antivirus software installed on this computer

Try the following
Download Dr.Web CureIt to the desktop from this link
ftp://ftp.drweb.com/pub/drweb/cureit/drweb-cureit.exe (http://\"ftp://ftp.drweb.com/pub/drweb/cureit/drweb-cureit.exe\")

Double click to run Dr.Web-cureit.exe from desktop

• Allow to run the express scan
• This will scan the files currently running in memory and when something is found, click the yes button when it asks you if you want to cure it. This is only a short scan.
• Once the short scan has finished, Click Options > Change settings
  
• Choose the "Scan"-tab, remove the mark at "Heuristic analysis".
• Back at the main window, mark the drives that you want to scan.
• Select all drives. A red dot shows which drives have been chosen.
• Click the green arrow at the right, and the scan will start.
  
• Click 'Yes to all' if it asks if you want to cure/move the file.
• When the scan has finished, look if you can click next icon next to the files found: (http://users.telenet.be/bluepatchy/miekiemoes/images/check.gif)
  
• If so, click it and then click the next icon right below and select Move incurable as you'll see in next image:
  (http://users.telenet.be/bluepatchy/miekiemoes/images/move.gif)
  This will move it to the %userprofile%\DoctorWeb\quarantaine-folder if it can't be cured.
  
• After selecting, in the Dr.Web CureIt menu on top, click file and choose save report list
  
• Save the report to your desktop. The report will be called DrWeb.csv
  
• Close Dr.Web Cureit.
• Reboot your computer

Post the report from Dr. Web and a fresh hijackthis log
