Before I can have you fix anything I need you to install Hijackthis to it's own folder
Yours is installed to your desktop - the reason for this is because if hijackthis is not in it's own folder we wont have any backups to restore from if something goes wrong
So go to my computer -> C:\ -> create a new folder called hijackthis and move the .exe file there. After this run a new scan and attach so that I can see this has been done
