BTW, I forgot to mention that it's usually better and faster, if issues get first addressed in the VirtualBox forums. More than 95% of the issues are resolved over there, 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".
After making 110% sure that Hyper-V is disabled in the Windows Features, you might want to make sure that Fast Boot is disabled and do a cold boot (i.e. shut down the host for a minute or two).
You also must make sure that nothing else is using Hyper-V, things like antivirus, debuggers, emulators, etc. Check out the articles "Diagnosing VirtualBox Hardening Issues" and "I have a 64bit host, but can't install 64bit guests" to get some ideas...
