BOAC Many thanks, that's what I need.
le pinguoin ? Not sure, I think I clicked on a link that I "thought" was from Windows, which I now presume wasn't, looked genuine and after my long absence I wasn't surprised at the reminder. Can't really blame Windows for that, the issue of blame, apart from own stupidity, presumably lies in the Virus Protection programme, McAfee, for which I hadn't paid, being provided as a "service" by my local ISP allied to Yahoo !
Kicked McAfee into touch and paid for Norton. Time will tell.
