Moved it to Malware Discussion > Artemis so the people from the lab can spot it hopefully.
Maybe the software changed in the interim? Just a thought.
If something is identified, maybe wrongly as "Artemis" then McAfee already knows about it. Merely send an email to firstname.lastname@example.org with the Artemis detection name and the words "False Artemis!++++++++++++" (where ++++ is the 12- digit code given to it) as the subject line. (Minus the "").
