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,
