Unable to build EXE using 6.0.0 but works fine building with 5.13.2

[bigwhoopgames]

Hello,

I understand this might fall into the antivirus false positive area, however because the application builds on the older version I figured this might be something introduced in 6.0.0.

When trying to build the program using 6.0.0 I get the following error:

Please let me know if there is anything I can do to help investigate what might be causing this difference between 5.13.2 and 6.0.0.

Thanks for taking a look.

Please let me know if there is anything I can do to help investigate what might be causing this difference between 5.13.2 and 6.0.0.

The difference is that they have different checksums. Most antiviruses don't read code – they just memorise parts of the file so even something as benign as an MSVC build version number change is enough for an antivirus to give a different classification.

This is quite common after a release since one of the malware classifications (called an artemis) is defined as a piece of software that no one had seen then suddenly lots of computers have seen it. You can imagine how that plays out when we release something and ~20,000/day Windows users start installing it...

[linxcow]

I had the same problem every attempt to create an exe with 6.0.0 was terminated by bitdefender.
Using the previous version works great for now

This is quite common after a release

Do you happen to have any experience in how long this usually takes to settle? I am still seeing interference by Windows Security's "Virus & threat protection" for 6.0.0, and defining exceptions is disallowed by group policies.

I'd say it's a bit pointless to speculate about this, because the next release will require bootloaders to be rebuilt again. Which might remedy the situation, or (more likely) make it worse by "prolonging" the settling period due to new set of binaries. Or perhaps they will be similar enough in the eye of the AV engines that it won't make a difference. Who knows.

[rokm]

You can always try rebuilding the bootloader yourself, and see if that helps. If your toolchain is different enough from what we used, the executable might end up being different enough as well.

And if you compile the bootloaders yourself, you can be even more certain that they indeed do not contain anything suspicious (as long as you can assume that your machine and toolchain are clear). The pre-built bootloaders are there for convenience, but they come at cost of implicit trust (not to mention that if I were to build malware with PyInstaller, I would definitely opt to use pre-built bootloaders, as that would increase the chances of my generated executables going undetected among other, legitimate, PyInstaller-built executables).

[bwoodsend]

The bootloaders are no longer being flagged as malware on VirusTotal by any of the commonly found antivirus vendors including MS Defender. If you're still seeing issues then you probably need some engine update/database resync to happen on your computer.

It is not true. I spent time creating a report for pyinstaller that the popular Avast joined the false positive. But the developer immediately closed it and marked it as spam. Inappropriate reaction to what is happening (no spam).

If you're still seeing issues then you probably need some engine update/database resync to happen on your computer.

MS Defender update: Ran Windows updater today, it found Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.399.1075.0). No longer blocking build (didn't even have to reboot my computer). 👍
