Issues with removing ssdbus.sys and ssudmdm.sys drivers.
Issues with removing ssdbus.sys and ssudmdm.sys drivers.
Running an older desktop with Windows 11 and Windows Defender. Memory integrity is disabled in Defender due to four incompatible drivers, including ssudbus.sys and ssudmdm.sys related to a Samsung mobile device. I'm unsure how these were installed initially, as I haven't connected a Samsung device to the system before. I tried deleting them but couldn't locate them in Device Manager or Task Manager. The remaining two are atikmpag.sys, which pertain to a video card driver and have not been addressed yet.
To address the ATI driver, it is suggested to download DDU from the provided link, restart in Safe Mode, execute the program, and eliminate any instances of the ATI drivers. This should resolve the issue. Regarding Samsung mobile device drivers, you may want to check the Add or Remove Programs section to see if they are listed; if not, consider installing them using the driver found at the given link and then uninstalling it afterward. You might also find helpful information in these resources about similar problems: memory integrity can't be activated due to incompatible drivers - Microsoft Q&A.
I removed the two SSD drivers by installing the Samsung driver and then uninstalling it.
Tried deleting the ATI drivers but faced issues starting in safe mode. The screen for safe mode shows the keyboard is not responding, and pressing 4 doesn’t work even after a minute. I explored other methods but had no success.
EDIT: The keyboard was disabled in BIOS; I re-enabled it with the mouse and removed the GPU drivers using DDU, which allowed me to enable memory integrity.
Thanks for your assistance.
Are you operating with a wireless keyboard? It's rare but it might have reset the driver during Safe Mode based on the manufacturer. In the worst case, switch back to normal mode and check System32 and System32\drivers for those ATI files.
It is a wired keyboard. I removed the GPU driver in safe mode, which restored memory integrity. Now Windows cannot install the GPU driver because of this setting. I tried to install it manually but couldn't find my GPU listed on AMD's site. It was an ATI Radeon 5800. I saw 5700 and 5600 models but not a 5800 one, and it also appeared under legacy settings. It seems the only options are to use the basic driver without worrying about appearance, disable memory integrity so Windows can install it, or try a newer card—though I'm unsure if that will work either.
Check the site for the correct driver information for this model.
I will attempt that. I saw Windows 11 isn't listed, would it matter if I chose Windows 10 instead?
EDIT: I installed the Windows 10 64bit version and it did install, but nothing seems different. Windows still suggests a resolution of 1024x768 when it should be 1920x1080.
I tried updating the driver software for the GPU in Device Manager and it starts installing, but it stops eventually with a message saying the driver can't load on this device. That driver was the one blocking me from enabling memory integrity in Defender.
unlikely to locate a Windows 10/11 driver for a GPU from 2009 that doesn't trigger that error.
if you're using Windows 11 and the main issue is defender, consider switching to another antivirus.

The situation is significant because disabling memory integrity can affect system stability and performance.
