No virtual machine on Oracle virtual box and Avira

December 2015, I suddenly cannot run Oracle VM Virtual Box (5.0.10) on Windows 7, my desktop machine. It failed to create a virtual machine, the error message is the following.
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)
I relatively less use the virtual machine on this desktop machine. But when I would like to use Linux, then I need to reboot the machine. This is inconvenient.

I have another windows 7 notebook, but I don't have this problem. Today I found the solution.


The combination of Avira's process protection and Virtual Box cause this problem. Avira announced the real solution will be provided at the release of 9th of Febrary. You can find two types of workaround on the page above. My notebook uses other virus checker from other company and that has no problem.
