When I install QGIS 2.14 and 2.18, Kaspersky gives me a Dangerous Object message. Below is a screen shot of the quarantine.

This - in my humble opinion - seems to be a "false positive". I uploaded it to virustotal.com and 0 of 56 scanners gave an error (last analyis ~ 2month ago). I forced virustotal to reanalyze the file and now one scanner from 56 scanners gave an alert : Kapersky.
You should send the file to Kapersky for analysis, so they can update their virus-definition file.
Unfortunately, these false alarms happen from time to time, for example
As Kurt already mentioned correctly, it is best to inform the antivirus provider.
