Hello

I've created a new Ubuntu 64bit VM to run on my Windows 7 host. When I start it, I pointed it to the Ubuntu ISO and click Next. It then indicates that it is starting and a few seconds later it fails with the following error:

"The instruction at 0x0f675b60 referenced memory at 0x0f675b60. The memory could not be written. Click on OK to terminate the program."

Here are the details of my environment:
1. Using VirtualBox 5.0.6 r103037. I have installed the Guest Additions.
2. Host is Windows 7 Enterprise SP1 - 64-bit with 8Gb RAM running on Lenovo Thinkpad (graphics card is Intel HD Graphics Family)
3. Guest is ubuntu-14.04.3-desktop-amd64 - I've provided it with 4Gb RAM.
3. VBox.log attached.

My colleague is experiencing the exact same behavior on his laptop (exact same model as mine). He has indicated that it he did not experience any problems in the past and that it just stopped to work one day. Even his working VMs from the past does not launch anymore. We are thinking that it must be IT update rollouts which are causing the problems, but can't pinpoint it to something specific. His thoughts are that it might be anti-virus related (we are now using McAfee v4.8.0.1923 and there is also something called Avecto Defendpoint running in the background).

Any help would be much appreciated.
Thanks,
Jaco

Can you please ZIP and attach the file "VBoxHardening.log" located in the same folder as your "VBox.log"?

Thanks for the response.
Requested file attached.

You have a lot of messages about "lacks WinVerifyTrust". I would suggest that you run "sfc /scannow" from an elevated privileged command prompt. A second step would be to search for "lacks WinVerifyTrust site:forums.virtualbox.org" to see what other have been dealing with...

Hi Scoratis

It seems there are conflicts between the VirtualBox Hardened Security and either McAfee or Avecto Defendpoint as we have been reading in the following forum thread:
viewtopic.php?f=6&t=67840&start=165

We have rolled back VirtualBox to version 4.3.12 which is apparently the last version without the hardening feature.

The only issue we found was that USB 3.0 XHCI support is not available in 4.3.12, so we needed to hand modify the *.vbox file, removing the <Controllers> section below:
<USB>
<Controllers>
<Controller name="xHCI" type="XHCI"/>
</Controllers>
<DeviceFilters/>
</USB>

With this change both the Ubuntu 14.04 and CentOS7 images work OK.
