This driver came with the computer when my friend purchased it. Virus scan may not find any thing but the driver causes a serious problem with the security because it prevents Windows 11 turn on the core isolation making the system vulnerable to access from outside. My Windows 11 also came with similar problem with a driver, igdkmd64, as if it was planted on purpose.

So I basically have 0 knowledge about this type of little detail. But my window recommend me to turn on "Memory Integrity" but these things (I don't know why they are 4 of them) prevents me from turning it on for some reason, so my question is should I delete it? If so, how do I do it?
