To help prevent the spreading of things like 
this. . . You should always be alert to messages 
with attachments. ALWAYS ask yourself:

1) Who is it coming from?
2) Do I know that person? Did they say they were
   sending something?
3) Is the message *written in* a style that person
   uses? (IE: If the person always uses a certain
   signoff, is that signoff used?)
4) What is the file? (.txt, .jpg, .exe, etc. . .)

Anything strange about a message with an 
attachment should throw up a red flag, as well as 
any attachment with a "false" extension (ie: if 
it looks like: "filename.jpg.exe") or a name 
completely unrelated to things you usually get. 
If you are any kind of suspicious, check back with
the person and make sure they really did send it 
BEFORE you open it.

And obviously, when in doubt, DELETE!

Thus ends my public service announcement. ^_^;
