i am experiencing the same issue, but only in my python 2.7 conda environment. It works in the base python 3.6 environment. When i try to extract the local\temp\PyInstaller-3.3.1.tar.gz i get a warning from Windows Defender it thinks the archive has a Trojan (win32/tiggre!plock)

Please contact you anti-virus vendor. There is nothing we can do about this false positive.

If your anti-virus vendor considers one of the files included in the PyInstaller distribution or a file generated by PyInstaller to be malicious, there is nothing we can do about this. Even if we'd change our code, they'd change their pattern and the race starts again.

Just another data point: I am experiencing this problem as well after updating from PyInstaller 3.3 to 3.4. I'm using Python 3.5. I wrote a blog post about the issue. I submitted my app to Windows Defender as a false positive, via their online form. Hopefully this will help.
