Some of the parasites can be really persistent...
Please run HijackThis again, but this time in Safe Mode. (To get to Safe Mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" as shown below. Use your arrow keys to move to "Safe Mode" and press your Enter key.) You may wish to print out these instructions prior to booting to Safe Mode, or copy them to a Notepad file.

and click 'Done'
Click the Traffic Light icon to start the program, and OK the prompts to reboot your PC.
Now restart the computer. You should get back to Normal Mode. Then run HijackThis again and post the new log in your new reply. Let's see how it goes now.
