I'm using Windows 10 64bit with all updates. Windows Defender Antivirus Definition 1.269.1192.0 (latest version)
I just manually scanned:
- NCrunch_VS2017_3.17.0.2.msi
NCrunch_GridNodeServer_3.17.0.2.msi
But didn't find any virus/trojan. Maybe Microsoft has fixed it.
Windows Defender becomes more aggressive recently, it reported 2 installers from JetBrains as trojan too.
