Couldn't do it there either. Finally found a solution by going to PnpUtil in Powershell and deleting the oem34.inf. Rebooted, and now my Core Memory is protected. Not sure why Brother products were being installed, as I do not own one. Their website was useless.
The printer driver that is screwing with my system BrUsbSib.sys does not show up in any of those listings. I DO NOT have a Brother printer, but this driver is incompatible. How do I delete it???
