Norton decided that VdosSetup.exe was malware and summarily deleted it.

Behavior
WS.Reputation.1 is a detection for files that have a low reputation score
based on analyzing data from Symantec's community of users and therefore
are
likely to be security risks. Detections of this type are based on
Symantec's reputation-based security technology. Because this detection is
based on a reputation score, it does not represent a specific class of
threat like adware or spyware, but instead applies to all threat categories.
The reputation-based system uses "the wisdom of crowds" (Symantec's tens of
millions of end users) connected to cloud-based intelligence to compute a
reputation score for an application, and in the process identify malicious
software in an entirely new way beyond traditional signatures and
behavior-based detection techniques.
