Of course the media loves to hype these things, but I think that this was
a valid case for some extra attention.  Not only was the worm particularly
destructive (just one single infected machine on a network could have
destroyed all files in a shared folder on a file server that the machine
had access to), but early copies did manage to get through the virus
scanners and MailScanner itself.  I have not come across that situation 
since the Bagle worm with its password-protected zip files.

Because we log the attachments that are sent to users we were able to
determine that 6 of our 2500 members had received copies of the virus in
uuencoded form.  One of those 6 then opened the attachment with WinZip and
got infected as a result.  Fortunately we were able to clean up their
infection before Friday, so no damage was done.

I think the media hype was a useful wakeup call to ordinary users to get 
them to update their antivirus software and to keep backups on separate
