Drawbacks on disabling hardware-assisted virtualization
« on: June 16, 2020, 02:16:23 PM »
Hi

Does anyone know the drawbacks on Disabling hardware-assisted virtualization? What protection features are affected/limited?

Recently started using Bluestacks and that requires virtualization. With Avast virtualization enabled, Bluestacks is very slow/non-responsive.

I'm not aware of any protection aspects related to the hardware-assisted virtualization other than to try and speed and isolate scans.

Perhaps there might be if virtualisation/isolation of a possible threat.  I haven't got it enabled, but I think that the paragraph in the Settings > General > Troubleshooting section would give a good idea.

Hi Alikhan,

CPU virtualization extensions Intel VT-x / AMD-V allows us to perform filtering of some low level system operations. It is currently used by sandbox/self-defense/anti-rootkit. The protection is slightly limited without virtualization, but nothing crucial. In most cases there is some fallback mechanism implemented, not requiring CPU virtualization.
