Sorted it!!...
for anyone else (using Vista and possibly Win7) that wants to know CCleaner won't remove the AutoRun, yes it will remove the 'Orphoned' bits and bobs left over from the install.. but not the extra crap in the 'AutoRun'...
The way to remove the entry is (drumroll please!!!)...
When the 'AutoRun' pops up, click on the 'Useless' entry and Windows will pop up an Error message saying summut like 'Can't find the Application' and it nicely removes it from the list!!!
I only found this out a minute ago when I got annoid and shouting "Look you Stupid XXXXing thing it's not there any more!!!" at my computer, I clicked the entry... et voila... it did the above for me!!
Sometimes Anger and Windows works!!
