Artemis detection questions should probably be in the Artemis forum http://community.mcafee.com/community/security/malware_discussion/artemis rather than here ... I'm sure a moderator may move this over for better attention.
I've had a look at your video, and also downloaded the same file and have done some analysis. The detection you are seeing isn't the only one that McAfee will flag in certain circumstances about the file and final installed products. Not sure if these are legitimate detections or McAfee being way too sensitive.
As for why you get the detection when you scan the installer, but not the installed product is because the files aren't referred for an Artemis check when installed - but only when compressed in the installer. It's hard for me to explain, perhaps someone from McAfee wants to explain why - it certainly isn't an answer I've had answered properly before....
Responded to duplicate thread in the Artemis forum and am locking this thread.
