I am working on a corporate PC Windows 10 Enterprise x64. 6 months ago I was given this PC with VirtualBox version 5.1.30 and I created a new virtual machine which worked succesfully till one week ago. Since then I am not able to run the VM anymore, I suspect that after an update of the WIN10 operating system.
I am working on a corporate PC on the network of the customer so it is not easy for me to uninstall/install software
Though I updated VirtualBox to current version 5.2.16, but I still get this error More than one thread in process
On the PC is running Triton endpoint that I can disable but nothing changed,
Avecto Defendpoint, that I can not disable and which according to the log seem to give problems
Symantec endpoint protection that I can not disable
I enclose the VBoxHardening.log
Can you please help me
