[C++] UserMode EasyAntiCheats x86

[MRx86™]

N.B this post was prev posted from me on others forum. some screenshot are missng

they also query PC Information from user mode.
they access to many registry folder.

they also perform a memory scan by calling ZwQueryVirtualMemory.
First scan 10 minuts later
Then every five minuts.
On the screen shot below
The Functions of memory scanner.
