Hi everyone! I am new to VirtualBox and unable to get it to work. I have a fully updated Windows 10 Home edition.
After several attempts I now uninstalled VirtualBox as well as my virus scanner, then rebooted and re-installed VirtualBox for Windows.
Next, I followed the instructions from topic 82277 to edit HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxDrv in the registry from 1 to 3 before rebooting. Then I rebooted.

in sum:

• Uninstall everything and then reboot.
  Uninstall Virus scanner and then reboot.
  Reinstall VirtualBox. DON’T REBOOT
  Change registry key to 3 for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\VBoxDrv
  Reboot
  Run sc.exe start vboxdrv in Windows Command Prompt.
  Run VirtualBox

When I try to start a virtual machine, I get the error: "Error relaunching VirtualBox VM process: 5" (log below)
I've run out of ideas what to do. Any ideas are highly appreciated!

Log details:
[ModEdit; removed partial VBoxHardening.log]

Partial logs are not that helpful I'm afraid. Please ZIP and attach the full log. See the "Upload attachment" tab below the reply form.

@socratis, thanks I've added the zipped log to the post

You do have a hardening problem:

108c.4270: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0x1 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 5049 ms, the end);

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.

I would start by completely uninstalling the following, or adding an exception for all-things VirtualBox:

108c.4270: supR3HardenedWinFindAdversaries: 0x1000
108c.4270: \SystemRoot\System32\drivers\vsdatant.sys:
108c.4270:     ProductName:     ZoneAlarm
108c.4270:     ProductVersion:  15.1.29.17237
108c.4270:     FileVersion:     15.1.29.17237
108c.4270:     FileDescription: ZoneAlarm

Thanks a lot!

I uninstalled my Firewall (ZoneAlarm) but VirtualBox still didn't work and produced the same error. I had disabled real-time monitoring of my virus scanner.
Then I also uninstalled my virus scanner (Avira). Now VirtualBox worked!
I again re-installed my virus scanner. VirtualBox still worked, even with real-time protection enabled.
Then I again reinstalled ZoneAlarm Firewall. And VirtualBox still works!

Strange... since I'm quite certain I have done the above before. If the problem does return, I'll post again. Thanks for the assistance!

Funny, it didn't show up in the hardening log...

It's not that strange if you re-read the Diagnosing VirtualBox Hardening Issues, you'll see one of the reasons, actually the reason... A program's signature that wants to get into VirtualBox memory doesn't match what's stored in the Windows Certificate Database (WCD), and the program is rejected.

By re-installing the two programs you must have forced the WDC to be updated, making everything work as intended...

Marking as [Resolved].
