Could be a false Artemis detection : I downloaded from CNET using Firefox. FF scanned for viruses on the way down and found nothing.
Saved it, scanned with Malwarebytes, McAfee, and Spybot : all of them gave it the all-clear.
The file does not have a digital signature to identify the publisher, which doesn't help. See below.
Submitted it to VirusTotal : 4 out of 43 marked it as malware - 2 McAfee and 2 others (NOD32 and PCTools).
There is a document here which should help you to submit a report of a possible false positive. The place to report Artemis FP's is at https://community.mcafee.com/community/security/malware_discussion/artemis
The Artemis number is Artemis!4FE7146EC509
