There are viruses being sent round at the moment which are hidden in
attachments. The covering emails seem to be official, from banks and so on.
Some of them threaten to cut off your ISP.
Anyone sending an attachment will mention it in the header or the body of
the email so delete the email if you don't recognise the sender.
If you think you know the sender but the body of the email doesn't mention
an attachment delete the email.
