Not sure the best place to ask this but the past 3 days we've had users receive an unusual message at boot up. For no apparent reason, and through no initiation by the user, the BIOS start up asks "Activate virtualization technology?" With the option to either accept or reject.

While we know what virtualization technology does, we don't know what's causing this.

Our Windows machines are all 9470 / 9480 Elitebooks but they come in various configurations (ie different bios versions, a mix of W10 and W7). So far all the machines coming up with the issue are Windows 10. No data on firmware version.

Any ideas what could be causing this problem to appear out of the blue?

We aren't about to enable the technology without knowing what's causing this so we are just telling them to reject it.

Thoughts? Please advise.
