The virtual machine 'chrome crx and sni' has terminated unexpectedly during startup with exit code 1 (0x1).
More details may be available in 'C:\Users\USR\VirtualBox VMs\chrome crx and sni\Logs\VBoxHardening.log'.

Kod wyniku (RC): 
E_FAIL (0x80004005)
Komponent:

IMachine {85cd948e-a71f-4289-281e-0ca7ad48cd89}

VirtualBox freshly installed. I do not know if this matters, but on my computer I have the Python interpreter installed in versions 2.7.13 and 3.4.0 and Avast antivirus.

Where can I paste VBoxHardening.log?

Problem

The last entries in your log points to the uxtheme.dll file, one of the vital system files in Windows, which implies that you have a hacked version of it. ⁽¹⁾

As far as I know, there are two ways to get around this issue:

Solution A _{/ Ideal (...and arguably practical)}

You should replace it with an original copy of it (from an unmodified or non-hacked Windows installation). ⁽¹⁾

Solution B _{/ Fastest workaround}

There are other ways to start a virtual machine in VirtualBox.

Use Headless start, it worked for me.
