About False Virus Detection Warnings - staxrip/staxrip GitHub Wiki

StaxRip employs mod versions of some tools in order to meet the need for advanced features such as Unicode(UTF-8)/long file path support, additional options for portable frameserver dll files, etc.

In this course, some of the mod tools are released as compressed by the open source exe compression tool UPX in order to save drive space drastically, and this may result in false virus detection warnings with some anti-virus software engines.

You can check that those same executables have no problem when uncompressed by UPX and submitted to VirusTotal.

For reference, see this issue thread, and this post on Doom9's forum.
