Hi...

Recently I have been receiving emails with the following message and two attachments (one is Att00055.dat and the other is a Mail Delivery (failure [email][e-mail][/email])):

"Subject: [WARNING: VIRUS REMOVED]Returned mail:see transcript for details

The original message was received at Fri, 22 Jun 2007 10:34:44 +0800
from bb220-255-154-243.singnet.com.sg [220.255.154.243]
