Ok. First things first. I am a stickler for ppl following only the instructions given. Although it is good that you have indicated everything you have done, doing things that are not requested can create a lot of confusion for the helper (namely me).
If you can stick to just what I request you do, I would appreciate it. You can run all the programs you wish once we are finished.

Deal?

Can you please do the following.

===============

Scan with HijackThis and then place a check next to all the following, if present:

Please then reboot your computer in Safe Mode by doing the
following :

• Restart your computer

• Choose your usual account.

• In Safe Mode, right click the SDFix.zip folder and choose Extract
  All,
• Open the extracted folder and double click RunThis.bat to
  start the script.
• Type Y to begin the script.
• It will remove the Trojan Services then make some repairs to the
  registry and prompt you to press any key to Reboot.
• Press any Key and it will restart the PC.
• Your system will take longer that normal to restart as the fixtool
  will be running and removing files.
• When the desktop loads the Fixtool will complete the removal and
  display Finished, then press any key to end the script and load
  your desktop icons.
• Finally open the SDFix folder on your desktop and copy and paste the
