Avast Business interferring with VirtualBox

Hello,
Anyone having issues with VirtualBox Linux VM’s. I have an ActiveCollab Linux machine running on Virtualbox. With AVAST installed on the host computer (Win10 Enterprise), it becomes very laggy and unresponsive via the web interface. I have tried adding in the Firewall exceptions and allowing all ports, and it does not help. Disabling the firewall, doesn’t help…disabling all shields doesn’t help. I uninstall AVAST completely, and it works like a champ.

We are running the most recent build AVAST Business 18.5.2535 (Build 18.5.3931.358) on Windows 10 build 1803 (17134.228)

Cannot have this working in this manner, if I cannot get this resolved I will have to cancel our subscriptions and find another solution.

Can you try disable “Enable hardware-assisted virtualization” in Settings->Troubleshooting ?
