Be cautious about opening e-mail attachments which appear to be an electronic Christmas card. F-Secure reports that the zafi.d virus is spreading on Windows PCs at the moment. The virus displays a Christmas greeting in the language of the recipient and spreads by mailing itself to other persons in their mail address book.
It opens a back door on infected PCs, making it possible for hackers to use them to send unsolicited bulk e-mail or spam, and to launch malicious attacks on web sites. Better to stick to sending real cards, if you haven’t missed the last-post-by-date already.
