One of my flocks asked this question and so I took my seld around to see what was what.
New short cut Icon had appeared on screen without bidding
Not wishing to risk his machine to mischief I ran Revo Uninstaller and deleted the program.
Lo when I next looked at my desktop I had it too.
So I had a poke around - and considering that I would not need it deleted it here too.
So where did it come from unbidden?
Is it a Windows IE /Firefox add on or what?
