Moved my post from other topic because this one seems to be more active and relevant to the issue.
Does Virtualbox conflict with VMWare Player? Or Avira?
I had all of them (Virtualbox, Avira Free, VMWare Player) installed and running happily for some months but then one day I could not launch my VBoxes any more - all of them failed with supR3HardenedWinReSpawn. Some time ago I updated to 5.0.2. Still the same error. Then I made sure I don't have that Windows KB update which was mentioned in other threads about the same issue with 4.xx. Still no luck.
Then I uninstalled Virtualbox completely but before rebooting I decided to disable VMWare network drivers because I have already experienced some issues related to them; see this article:
https://stijndewitt.wordpress.com/2014/ ... angs-ie11/
This is useful for network adapters with broken driver support, as well as some virtual network providers such as vpn drivers, or spam, virus or spyware filters.
BTW, how would VirtualBox react to such broken drivers?
Anyway, I disabled the drivers (using Sysinternals Autoruns) and restarted the host and reinstalled Virtualbox 5.0.2. Hooray! It worked!
Then to make sure that the VMWare network drivers are the cause, I enabled the drivers again and rebooted. Yeah, VirtualBox crashes again with the same issue. Disabled the drivers, rebooted... oh, no, VirtualBox still crashes!
Now I'm not so sure, what's the problem, why did VirtualBox start crashing again - because I had enabled the VMWare network drivers once and then later disabled again or because I rebooted the computer after installing VirtualBox
Anyway, VirtualBox is broken again.
Running it on Windows 64 bit Pro with 8GB of RAM.
The log file is attached.

I have Avira Free antivirus, and it does not make any difference whether I have Real-time protection enabled or not.
Maybe it's time for more serious hacking with Autoruns and disabling all non-crucial drivers to see what happens.
I tried disabling every non-Microsoft driver with Autoruns and got carried away and got some BSODs pointing to hard drive problems
Restored from Last Known Good Configuration and started over, this time leaving AHCI and other, possibly storage related drivers enabled. Avira drivers were disabled, too. My sound stopped working and video reverted to low res, but still the same error from VirtualBox. It seems, there is no chance to find the problematic driver using lucky guess approach, if it's a drivers fault at all.
Unfortunately even if hide all Microsoft drivers, there are lots of crucial system drivers which cannot be disabled, and Autoruns does not tell which drivers have been recently added or updated, therefore it's hard to find anything.
Still I have gotten it working just that single time, straight after installing without VMWare drivers. Not sure, if it does mean anything.
Now I have just updated to 5.0.4, but still the same issue, see the attached VBoxStartup5.0.4.zip
