Newbie having trouble downloading..possible virus?

Hello, trying to download the “open-stage-control-1.8.2-win32-x64.zip” for a Surface Pro 4. It keeps dropping the download at about 40% and my anti-virus (Avast) pops up with “…infected with Win64:Trojan-gen”. Anyone else have this problem? Appreciate any suggestions for a workaround. Thanks, Graham

It’s a false positive alert
