Error when launching virtual machine

[Ilin]

I used Virtualbox a while ago with no issue. However now when I try to access a virtual machine I get the following error

Failed to open a session for the virtual machine jcyrf.

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

Result Code: E_FAIL (0x80004005)
Component: MachineWrap
Interface: IMachine {85cd948e-a71f-4289-281e-0ca7ad48cd89}

I have tried reinstalling virtualbox a couple of times but I still get the same issue. I have the latest version of virtualbox on Windows 8.

Please read really carefully the following FAQ: Diagnosing VirtualBox Hardening Issues for some generic guidelines/ideas. Remember, these are guidelines, not the exact solution, you have to use your judgement as to which program might be responsible.

We could potentially give you a suggestion or two if you posted a ZIPPED VBoxHardening.log (the one mentioned in the error) and we see signs of known applications.
