Mimail.C
The irritation has begun :/
A new version of Mimail.C has cropped up. It spoofs the recipients domain and
sends the mail as 'james@<spoofed domain>' and has an attachment:
pictures.jpg.exe
Some clients have reported massive amounts of lag due to its mass mailing and
one client's firewall dropped as a result, although this might not be related.
More info can be found on:

Antigen pics the attachment up as I-Worm.WatchNet
Keep an eye out and inform your users
cheers
