Usually if no big-name Anti-Virus products flag it, it's usually fine. For example, the three that flagged it are: "Fortinet", "Varist", and "Rising". Fortinet seems to have somewhat bad reviews, but really there's not much talking about it, so kinda sketch. Varist has even fewer things talking about it, even Google assumes you've mistyped Avast instead. Rising is a Chinese company that dropped support for English in 2013 and advertised using Machine Learning for their Anti-Virus, so kinda sketch as well.
Basically, all of those products are sketchy and probably can't be trusted to be accurate. Because the bigger names like Kaspersky, Avast, McAfee, etc. don't flag it and if Windows Defender doesn't flag it, it's probably fine. If you still don't completely trust it, then get a sandboxed version of Windows using VMware or VirtualBox and run it on that so it doesn't affect your main PC.
