I have been getting them as well, I suspect that they are being sent with viruses attached, (they always have an attachment). I immediately delete them without opening the attachment, and clear them out of ther recycle bin too. I have also had them purporting to be from my ISP, saying my account is suspended - they are all just ruses to get you to open the attachement, which will have the virus or worm or some other nasty. I do not think there is any way to stop receiving them, you can block the sender each time, but they are coming from many different sources.
