It is unfortunate that MalwareBytes has joined the club of mediocre AV companies pumping out false positives to get their hit count up. A member of the PowerBASIC forum found the name of the file that offended MalwareBytes, an archive written by "Test Department" before the year 2000 and as I could not be bothered testing over 50 tutorials, I simply replaced the full source and binaries with a source only archive. Its there for folks who want to write a very old style of 32 bit assembler, it would be of very little use by modern standards.
I replaced the file "td_win32asm_all.zip" with "td_src_only.zip" and fed it through VirusTotal with no false positives recorded.
As far as MalwareBytes, a few basic lessons in who and what are the authority on file specifications, Windows (all) is produced by the Microsoft Corporation and the definitive specifications for portable executable file in Windows is PECOFF.DOC, not MalwareBytes. Noting that a ZIP file with content dating back before 2006 and actually written before 2000 does not comply with DEP, does not need a manifest or version control blocks, actually bothering to detect the file date is not hard to do.
At this moment I could not safely recommend anyone using MalwareBytes until they improve their performance.
