This is a generic detection of email messages generated by various W32/Bagle@MM virus variants. Since the detection is generic, it is not possible to state specific details in this description.
Please note: As this is a detection of the mail message itself, using specific identifiers about the mail message that are unique to the Bagle virus' email sending component, it is possible for this to trigger on email messages which have had the active viral component removed.
Additionally, because this is a detection of the mail message "as sent by the virus", if the message has been forwarded or "bounced" by an email system en-route to the recipient, it is possible for some samples which have had the virus attachment removed to be missed under some circumstances. Note: in these cases where this detection is missed, there will not be any active code if it's a known variant of W32/Bagle.
Customers should simply delete all email messages identified as W32/Bagle!eml.gen
