i want to make a antivirus in autoit with follow features.

1, process monitoring

2. behavior blocker.

3. use NtCreateProcess/Ex from kernel-mode to monitor process execution.

IAT hooking. Look into hooking:

- NtCreateThreadEx - hook this to block injection but you need to check parameters in the callback function to filter real injection attacks in case the program is just creating a new thread within its process

- NtAllocateVirtualMemory/NtWriteVirtualMemory - if these two functions are used on a specific process (get PID of process being targeted) and then it calls NtCreateThreadEx on that same process = injection attack

- NtGetContextThread/NtSetContextThread - look out for usage of these after process execution has been performed via NtCreateUserProcess and that same process has been suspended (main thread -> NtSuspendThread) = indicator of dynamic forking - NtWriteFile - hook and filter for hosts file, browser config files, etc. Alternatively use a file system mini-filter which is more efficient and secure

- NtSetValueKey - hook this and other registry functions and filter for UAC/SmartScreen/Windows Firewall/Windows Defender settings and also Run/RunOnce locations, you can check other areas too. Alternatively use a kernel-mode callback which is more secure and efficient

... ETC ... 

it's possible?

AutoIt is most definitely NOT the language for building anti-virus apps. Thread closed to prevent further waste of bandwidth.
