Py2Exe application flagged as malware by Windows Defender; what to do?
I used Microsoft's "Submit a sample" page to report https://pypi.python.org/packages/3.4/p/py2exe/py2exe-0.9.2.0-py33.py34-none-any.whl as a false positive on June 20, 2014. As of June 23, 2014 it was no longer detected as BrowserModifier:Win32/Zwangi or anything else.
Even the py2exe executable itself is being flagged as malware. It was discussed in http://www.reddit.com/r/Python/comments/26g157/py2exe_now_available_for_python_33/ - the latest VirusTotal scan shows 9/51 scanners finding malware in it.
I had this issue with pyinstaller too just build pyinstaller bootloader on your system and install rebuilt one, here is the link from the official website for instructions :

and btw use MSVC as your build tool i had no luck with GCC.
