How can I get rid of a specific driver that I'm not even using?

I am unable to turn on Memory Integrity in Windows due to an incompatible Logitech driver. I no longer even own a Logitech webcam, and this driver has not been updated since 2012 (hence the warning).

lvbflt64.sys

I checked in C:\Windows\System32\Drivers and the file is not there.

I checked Device Manager and the web cam isn't even listed (even when Show Hidden is on).

I do not have any Logitech control panel type software on my machine.

How can I find and remove this driver so that I can turn Memory Integrity back on? Getting highly technical doesn't scare me off, I just want it gone.

When I search on disk, I see these in the DriverStore. I have tried every trick I can think of to remove these, I can't. They require SYSTEM level permissions to remove manually.

The reason I'm going through all of this pain is to get rid of the insecure flag that Defender shows in the taskbar. I fully understand what Core Isolation is/does, I am a software engineer.

I just want a clean system and I don't want Logitech drivers from 2012 on my machine when I don't even use Logitech devices. And these drivers are now interfering with system security.

In the device manager:

Select View → Devices by driver
Right click on the driver (in your case oem109.inf)
Enable both tick boxes:
- ✓ Uninstall this driver from any device that currently use it.
- ✓ Attempt to force remove of this driver while it is still in use by the devices

(reboot the system)

what do you get from starting cmd as administrator and running cd \ + enter + dir *lvbflt64* /s /b ? (the last command might take a while, especially if you're not on a SSD)
