Bonjuor Francois,

This may well be linked to a bad .dll or even a worm/trojan attached to one
of the processes running under svchost. I would try a good .dll checker and
complete a full virus scan from within safemode.

If that doesnt work, then I would disable each of the items under svchost in
turn and restart after each one. That way you will identify which of the
elements are at fault.
