Thanks for the report, we will be investigating this right away.

Is there any more information from Malware Bytes as to what malware it thinks this is?

This seems to be the package from above list/version that contains pngfix.exe: https://anaconda.org/anaconda/libpng/1.6.37/download/win-64/libpng-1.6.37-h2a8f88b_0.tar.bz2

Can you please report the SHA256 checksum of the suspicious binary? In PowerShell, Get-FileHash -Algorithm SHA256 ANACONDA3\LIBRARY\BIN\PNGFIX.EXE.

Unfortunately, all that Malware Bytes provides is above. I did some web research and couldn't find anything more on this auto-generated name. Which likely means it's not popular/frequent. Also, from that research, there are a few posts indicating that MB's AI generated malware signatures has false positives. It's possible this is a false positive.

That file is indeed in the above mentioned package (command works on macOS):

wget -qO- https://anaconda.org/anaconda/libpng/1.6.37/download/win-64/libpng-1.6.37-h2a8f88b_0.tar.bz2 | tar -xOf - Library/bin/pngfix.exe | shasum -a 256

The output b0d51843324f2872d2a7e7ff74fe53908adc769bb05f75af1c95b5462a72ded6 - matches the provided sha256.

Uploading that file libpng-1.6.37-h2a8f88b_0.tar.bz2 to virustotal.com gives it a score of 0/57 (=nothing found by 57 different virus/malware scanners), see https://www.virustotal.com/gui/file/20a69e29fe0c6d9d333d23c9566078e4afabcdef631a28125bfcf76743a8a9f7
