I am no " Guru" by no means. However after doing a search on the above mentioned Artemis Detection. Sophos detects this as (Troj/Agent-RAQ). Being uncertain if you are using a Consumer version of McAfee, or not. One quick way to assist you and submittal of this file to McAfee, is by running the Latest Getsusp tool. Also you may want to visit the link to Microsoft in this other thread, in which I posted in regards to another "Artemis Detection".
Hopefully one with more knowledge will pick up this thread,and assist.
As CD says try the getsusp tool and they will test anything found by it
That ssaid you can submit the file as per
When you get the auto reply saying it is infected reply to it changing the subject to false +ve and name of detection say why you feel it is safe and post the analysis id number here after you send off the email. If no fix in 4 days post back and I will chase up a tech to sort things out.
