I've had a dreadful scare recently.
Last year, I was the 'honoured' recipient of one of the Nigerian scams, accessing my contact list and asking for money. I changed e-mail; accounts and as a birthday prezzie, was given a lovely new laptop.
Fine, until last week, when I became aware that a 'failure notice' had been served on one of my e-mail contacts to whom I knew that I hadn't written to for some time. So, I accessed the notification record from the e-mail provider, to see, to my horror, that my account had been accessed from Venezuala, Japan and Spain.
As per advice from Y****. I have changed my password and as of this moment, all is well, but it leaves me feeling as if someone's intruded in my life and I don't like it!!
