Version 5.0.10 r104061 fails to start any VM on Win7x64 (Avira)

[Timbo]

After the Update to 5.0.10 r104061, i get the same error on two different host systems with Windows 7 x64 (amd & intel systems), no matter which kind of guest vm i'm trying to start.

60 sec after starting a vm the following error-box appears:

VirtualBox - Error In supR3HardNtChildWaitFor Timed out after 60001 ms waiting for child request #1 (CloseEvents). (rc=258) where: supR3HardNtChildWaitFor what: 5 Unknown Status 258 (0x102) (258) - Unknown Status 258 (0x102)

If i click on "ok" the following error pops up (german version):

Für die virtuelle Maschine "vmname" konnte keine neue Sitzung eröffnet werden. The virtual machine 'vmname' has terminated unexpectedly during startup with exit code 1 (0x1). More details may be available in 'C:\ ... \VBoxHardening.log'. Fehlercode:E_FAIL (0x80004005) Komponente:MachineWrap Interface:IMachine {f30138d4-e5ea-4b3a-8858-a059de4c93fd}

If i don't click "ok" and just wait, the first error-box appears a second time with the "ok"-button blacked out and the vm boots normally i think. But the two identical errors stay and if click on the blacked out one (ok) later the vm is closed immediately.

That's some conflict with Avira. See ​here.

Replying to frank:

You're right. They have another workaround there, which isn't working for me and many others. So uninstalling Avira is a solution (not really :-) or as i allready said, waiting (about 2-3 min) and ignoring the errors. U can click away the first (not blacked out) error after the vm started.

Here is some discussion too ​https://forums.virtualbox.org/viewtopic.php?f=6&t=74917

Hello, I have similar issue, seems that's a new bug. Only ignoring 2 boxes is the way right now, and If I try to close the boxes clicking "OK" VM stops. https://www.virtualbox.org/ticket/14905

Hi, I had same problem "supR3hardNtChildWaitFor", VirtualBox 4.3.20 r96997 and I resolved unistalling AVIRA.

Same problem here. I had the latest version of Avira Free installed. I hadn't started my VirtualBox (then 5.0.10) for a while. Doing this resulted in the same error of the TS. I first tried to update to 5.0.12 - this didn't resolve the error. I then removed and reinstalled the VirtualBox software again without resolving the error. Only after removing Avira from my system Virtualbox booted as normal. When I reinstalled Avira emerged again.

I also experienced this and filed https://www.virtualbox.org/ticket/14978

Is there any news on the part of Avira?

I am using win 7 x64. I also faced this issue after upgrading to 5.0.10. i uninstalled and reverted to 5.0.6 . issue is not solved.

i want to use vagrant to start my vm. it is failing now.
