It's usually better and faster, if issues get first addressed in the ​VirtualBox forums, a lot more eyes there. More than 95% of the issues are resolved in the forums, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

Plus a discussion and analysis on the bug tracker is going to help me, you, and potentially a future drive-by user or two. Not so in the forums, many more tend to benefit...

Having said that, you have a hardening problem. From your VBoxHardening.log:

160c.f95c: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0x1 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 1990 ms, the end);

Please read really carefully the following FAQ: ​Diagnosing VirtualBox Hardening Issues for some generic guidelines/ideas. Those are guidelines, you have to use your judgement as to which program might be responsible...

I'd start by completely removing, not simply disabling:

160c.f95c: Found driver klkbdflt (0x40)
160c.f95c: Found driver klmouflt (0x40)
160c.f95c: Found driver KLIM6 (0x40)
160c.f95c: Found driver kneps (0x40)
160c.f95c: Found driver klflt (0x40)
