  I don't know how you deduce that Z was referring to the Safari problem(s), 
I thought it might have been the one about the mailer failing to warn for 
some unsafe attachment types.

  Exactly.  Some of the most successful viruses recently have arrived inside 
encrypted zip files, with a GIF as an attachment, that contains a password 
in graphical format, and the user has to open the gif attachment and note 
down the password and open the zip and enter the password and extract the 
executable and run it.

  And they /did/, in their droves.

  No matter what kind of protection Apple put in place, no matter how 
quickly they fix drive-by-install vulnerabilities, no matter how big the 
warning dialog that mail pops up when it detects executable files and even 
if it isn't spoofable - people will still do it.

    cheers,
