Hi all
This is a warning of what is actually more a malicious email program than a 
virus or worm, but can still hurt the unwary. It is an email purporting to
be a fix for the "nimda" worm/virus, but is in fact a harmful program. If
you haven't heard of it yet, then you've heard now - be careful out there.

As always, AusCERT urges system administrators to inform their users about
proper precautions with regards to handling email attachments.

AusCERT recommends that sites should update and check their virus defences
and either delete or do not open any unsolicited email messages or
attachments that resemble those described above.  System administrators and
users are additionally urged to ensure that the latest Anti-Virus software
is installed and that it is using the most current up-to-date virus
databases.

The AusCERT team will be monitoring any new developments on this issue and
will release updates as they become necessary.

Regards,

The AusCERT Team
