[BC] is some new virus out there?

[Donna Halper]

This morning, when I began to download my mail, I noticed about 35 bounce 
messages, all from the postmaster at AOL, and all to people I had never 
sent an e-mail to.  I up-date my own virus protection software daily, so I 
am sure this one is not anything I sent out, but I am curious about what 
virus might be out there right now that is making such a strong 
re-appearance  MYTOB perhaps?  -- It has been mainly yesterday and today 
that I noticed all the weird e-mails.  Has anyone else noticed a sudden 
influx of "Returned Mail-- Service Unavailable" messages to addresses they 
didn't recognise?

Also, please straighten something out for me, in language that a non-techie 
like me can comprehend, please!  Is it still true that if you don't open 
any attachments, you are usually safe, since that is still how most viruses 
are transmitted?  I've been hearing that this old truism is no longer so 
true, and I figured that if anybody would know, it's the experts on this 
list!  (Keep in mind, I am mainly a user and don't know a lot about the 
tech end of things, so I rely on the kindness of my friends to enlighten me 
and keep me from being misinformed!)
