S M Bus Controller Driver not Installed

The reason for this is it does not require any drivers!

The SMBus is designed to automatically work with windows without requiring any drivers to talk to the device.

in the oem64.inf C:\Windows\INF\oem64.inf

%PCI\VEN_8086&DEV_A123Desc%=Needs_NO_DRV,PCI\VEN_8086&DEV_A123

is listed specifically stating that this device does not need additional drivers.

I found this information by going to the device manager and right clicked on the SMBus Driver, selected Properties, then in the next drop down selected Configuration ID

So this means that for a particular Trojan that uses the SMBus is effectively invincible to all attempts to remove it. Assuming that the trojan has not already embedded itself into your hardware, only way to know this is to reinstall windows and see if the infection persists through a fresh install. if so this particular type of infection may be irremovable depending on your particular skill set.

Hi,

We recommend you to uninstall the bus controller driver from the list of device manager. To do this, follow these steps.

1. Click Start, type devmgmt.msc and hit enter.
2. From the list of items, right click on the driver item and click uninstall.
3. Restart the computer for the changes to take effect.
4. The driver should be installed automatically after system restart.

Updating the chipset driver should help. To do this, try these steps.

1. Click Start, type devmgmt.msc and hit enter.
2. From the list of items, expand Processors.
3. Right click the sub item and click update driver.

Tried all the above suggestions-None worked.

I uninstalled, restarted computer, and it asked for a Driver CD-Tried the Operating System Disc but came up driver not found.

I'm still without a SM Bus Controller Driver

Is Driver Detective Product software any good for needed drivers-Advertised on the Internet. But not sure I trust them.
