Found when connected my MP4 player from Creative to my USB port, and started the scan, advised by McAfee.
Based on the Artemis detection, we were able to download and analyze the file, which is currently detected as Generic PWS.y!ti and Generic PUP.x (component). I would suggest you to update your DAT files and perform a new scan.
After that, if you are still receiving the Artemis detection, please submit us a copy of the files for further analysis. Instructions on how to do that can be found at http://www.mcafee.com/us/mcafee-labs/resources/how-to-submit-sample.aspx .
Hope this helps,
