  • You need to start using a code-signing certificate that has a SHA256 signature. As of January 1st, certificate chains containing SHA-1 are no longer trusted and result in this error.

  • By the way, this error was happening with official VirtualBox downloads for several months. Seems to be fixed now. Chrome had no problem with the VB downloads, so Edge must be enforcing a stricter standard.
