1. 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 not a bug and someone has to deal with it and close it as "Invalid".

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

2. The error is asking you to take a closer look at a specific file ('C:\Users\ADELIO\VirtualBox VMs\Linux 16LTS\Logs\VBoxHardening.log'). Did you? Can we also have a look?

3. 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...

4. If you still have a problem after reading through the whole thing, please head to the ​forums, and open a new thread. Please be sure to mention that you came from the bug tracker and include the ticket number.

EDIT
I just realized (after commenting) that this is a duplicate of #19136. Closing as such...
