Hi, looked through your hijack this report, the file which seems to be giving you problems is the one under blue yonder, if you remove that should be ok.
Have attached a little report on blue yonder which will tell you how to remove it from the registry, take a look at this, do as it asks ( if you have any queries let me know ) run your anti - spyware virus scans again and see what happens.
Remove the file from the registry in safe mode, that way it will not have a chance to run when you start your computer normally, just press F8 when your pc is booting up, once a second should be fine, then go to the safe mode options.
Follow the attached info from there, you might be better printing it out first so you can see it while you are working without jumping around screens.
