I see from your HJT log that you're using a 64 bit operating system.

Unfortunately, the tools we use to analyze and remove infections do not work properly on a 64 bit operating system, and their results cannot be relied upon. Because of this, it is almost impossible for us to correctly diagnose problems, and the fixes we might offer could potentially do as much damage to your computer as any infection you might have.

Due to the above stated reasons, we do not at this time offer support for 64 bit operating systems. We are sorry that we are currently unable to assist you.
