What To Do When McAfee Detects Software As An Infection - How to Submit To McAfee Labs & Appeal has instructions within you could submit to McAfee for analysis.
Anti-Spyware/Malware & Hijacker Tools contains some information to assist getting rid of malware and trojans. I suggest running the McAfee Stinger Scan and Malwarebytes (free version).
Some of the other moderators will possibly chime in to see how you are progressing and offer any suggestions that may also be of assistance to you.

Moved to Artemis
I somehow don't think this is a false detection. There's only one external reference I can find to this Artemis detection number and that's on a submission to HerdProtect where the overwhelming consensus (35 out of 68 AV engines red-flag the submission) is that what was submitted was the InstallIQ Installer, variously described as Adware, a PUP and a Trojan.
If the file is in a network shared folder disabling it varies slightly according to which OS you've got. Is it Vista, Win7, Win8, or another? Once we know that, you'll be able to disable the shared folder easily; and then McAfee should be able to scan the folder and quarantine or remove the file.
This is win 7.
All --- if McAfee detects a threat please consider that as a threat unless its confirmed to be safe... if you know the application that is being picked up only then the question of a possible incorrect detection kicks in.. just because a detection is Artemis does not necessarily mean its bad. you could co-relate the Artemis detection to being the immune response you see our body doing to new or strange diseases as an effort to combat them. (antibodies at work..)..
Now best course of approach would be to take a look at the Interface and see if points to a folder or location and that will help indicate what file has been detected
if there are no conclusive location (either due to long winding path or its missing as in this case) i would recommend taking a look in Quarantine section or as peter called out to see if its waiting for user to take action..
Finally (my favorite and the easiest way) if to take a log at the On Access logs ( a simple text file)-- from Start>run > c:\ProgramData\McAfee\VirusScan\Logs\OAS.LOG and attach that file as a response to the thread for helper to take a look
