Error on importing ova file

[Chunu]

Hi all,

I try to import a ova file which Ubuntu 64 bit is installed.
But, as starting the virtual system, it is failed to open a session for the virtual machine with following an error message.

=====================================================
The virtual machine 'vagrant_PreSales_Stages_RTC' has terminated unexpectedly during startup with exit code -1073741819 (0xc0000005). More details may be available in 'C:\Users\MDS\VirtualBox VMs\vagrant_PreSales_Stages_RTC\Logs\VBoxHardening.log'.

Result Code:
E_FAIL (0x80004005)
Component:
MachineWrap
Interface:
IMachine {b2547866-a0a1-4391-8b86-6952d82efaa0}
=====================================================

I think the ova file is ok, because the ova file is properly imported and started at other computers.
Information about my host environment is as follows:

=====================================================
OS: Windows 10(64bit), 1703 ver., 15063.540 os build
CPU: Intel i7-6500U 2.50GHz
RAM: 8GB
Virtual box version: 5.1.26
=====================================================

I attached a detail log file. Please tell me what is the reason and how to solve the problem.

Thanks in advance.

Please read the following FAQ: Diagnosing VirtualBox Hardening Issues. In your case, I believe it might be the Kaspersky antivirus that's responsible.
