Hi again.
in answer to
(1) to cut a long story short the supplier of my p.c turned out to be a bit of a shady character and used pirated versions of Windows O.S and I am informed of so when updates pop up.
(2) the settings on I.E were as you recommended set already.

if so I thank you very much for all of your assistance and your knowledge can only be admired.
