It's really strange. :(
Just to be sure, I have now scanned all the build files with Windows Defender, Malwarebytes and VirusTotal and everything looks ok on my side.
Maybe it's a problem with an unsigned exe file that Windows detects as potentially dangerous/from unknown source.
On my side, I can confirm that I haven't detected any viruses in the files, but I'll look into the it and with the next update I'll try to sign the executable file so Windows doesn't mark is as false positives.
