Paracab,
Secondly emails with attatchents are generally always from friends, and, I am expecting them.
As Richard has explained, these are the
most dangerous, precisely because you
are, to some extent, expecting them...
If you are using any of the Outhouse, sorry, Outlook family of products from MS,
please ensure that you have
all the security patches installed.
Better still, install
Mozilla Thunderbird or
Quallcomm's Eudora which, although they will not make you impervious to email viruses, will make it orders of magnitude more difficult for them to infect...
