I don't think there's anything we can do about this, other than convince 
more users of Norton Internet Security to use Python 2.7 (apparently 
Python 3.5 is more popular with that demographic :) )

The installer is signed with the PSF's certificate, which keeps Windows 
Smartscreen happy and is the only way we can indicate that it's 
trustworthy. If Norton requires different criteria then that is on them 
and not something we can fix.
