[Solved] Error installing VirtualBox on Windows 10

Note: this solution works only if you have Kaspersky (or probably other security/antivirus) software installed.

Default VirtualBox installation on Win 10 failed with error messages:

Oracle VM VirtualBox 5.0.12 Setup Wizard ended prematurely
Installation failed! Fatal error during installation

Software versions:

VirtualBox 5.0.12 released on December 18th, 2015
Windows 10 build 10586

I can complete install only with all networking features disabled (no bridged, no host-only - no networking at all).

Solution in my case: remove Kaspersky antivirus (trial version pre-installed by the laptop vendor). Seems kaspersky network drivers/shim caused failure of VirtualBox network driver installation.

Security vs convenience. Is it Oracle or Kaspersky behaving odd?..

Update.
