I know I don't need to tell any of you about this virus as you all keep
your definitions up to date, and would never click on an unexpected
attachment, but just in case: W32.Erkez.B@mm is a mass-mailing worm
that sends itself to the email addresses found on an infected computer.
When this worm infects a computer, it attempts to overwrite executables
associated with security products installed on that machine. This worm
does not use any exploit code in order to execute the mail attachment
automatically. A user has to doubleclick on an infected attachment or a
file shared via P2P to infect the machine.
Read for yourself:
"I think it says something about human nature that the only form of
life we have created so far is purely destructive. We've created life
in our own image"
