Let me second Jeff's advice to have a good anti-virus program running.  I
have Norton 5.0 and it didn't even give me a chance to open the message
with the virus.  It warned me as the message (with the infected Happy99
attachment) was downloading and gave me several options, one of which was
"delete immediately."  These programs are so cheap now and updating the
virus definitions is so easy (a one-click process) that anyone who uses the
internet (everyone on PedTalk, by definition) needs one.

Danny, before you dismiss class and we return to pediatric issues, can we
take advantage of your computer knowledge a little more.  How good a job do
you think the standard anti-virus programs do at identifying infected
attachments before they are run?  IOW, if we receive one of those "cute
little programs" and scan the program for viruses (with "scan compressed
files" enabled and updated virus definitions), would you still recommend
trashing the attachment if it comes up negative?  What are the odds of the
anti-virus software missing a virus under these circumstances?  And if it
misses a virus while the attachment is still a compressed .exe file,
should the anti-virus software then be able to identify it (and give us an
opportunity to delete it before damage is done) once the program begins to
run.  I recognize that computer virus hackers and anti-virus programmers
are in a continuous game of cat-and-mouse (and there are times when the
hackers are a step ahead), but what are your general feelings about the
effectiveness of anti-virus software?  Thanks for any thoughts.
