Note that the VirusTotal analysis is not what our malware scanners use to
identify malware, it's just something we can link to externally that
provides some reasonably extensive analysis of files. In this case, I agree
that the VirusTotal case looks a little sketchy, so I'll take a look at our
own scanners to see if there is something we should be fixing.

But in general, our scanners are quite good at not getting confused by
installers and the like. There are many many projects on our platform that
host installers in various formats that don't trip our scanners, and when
our scanners report malware with the severity we got for this file, I
haven't yet seen it be wrong. That said, as I stated above, I'll follow up
internally and see if this was a false positive, and kick the scanners back
into line if it was.
