First, I want to say that I used to be in the IT (computer world) for
24 years before having to switch careers to piano and related work.
Also, I have been keeping track of Microsoft & Windows shenanigans
since 1994 and after you read this you will be shocked:

As you know, 99% of the viruses and worms affect Microsoft Windows
operating systems.  Well, Yahoo email servers _run_ on Windows systems.
Whereas, most of you _don't_ know that over 80% of the Internet systems
are running Linux operating systems, Microsoft's competition!  As such,
Linux systems are _completely_ immune to Windows' viruses and worms,
etc.  So, one reason why Gmail is safer is because their email servers
are running on Linux.

Good luck,

 [ I have had two more reports from friends that their Yahoo accounts
 [ have been hacked.  I've always assumed that the issue was
 [ captured passwords via a "phishing" page.  A compromised Windows
 [ server might explain why these hacked-account events seem to come
 [ in waves.  A hacked server might give up ALL of the address books
 [ on them in one shot.   I've also been told that the outgoing mail
 [ attributed to these hacked accounts didn't end up appearing in
 [ the "sent mail" folder of the users.   This further supports the
 [ "server was hacked" theory.   I remain a Linux fan.   --Jody
