Kim hunted and pecked:
I have recently obtained a laptop which is Windows XP. It seems to
work fine except that I keep getting these grey boxes pop up from
"messenger service" from all different people inviting me onto their
web sites, I do not know how to get rid of these. Has anyone had a
similar thing? can anyone help me by suggesting how to get rid of
them?
