Thank you. I will merge your PR after I finish the separation of NanaZip.Classic and NanaZip.Modern. Please wait for me some time to finish that. Kenji Mouri |

The feature looks good to me. There are some steps needed.

I've enabled the DLL blocker for both projects. I'll leave the Detours part as is for the moment. |

Detours dependency integration is ready in NanaZip.Shared.Mitigations project. You can continue with this PR. I will merge this if you have done that. Kenji Mouri |

I've rebased the PR. |

To recall, #236 disabled the dynamic code mitigation on NanaZip's main FM thread due to an incompatibility with ExplorerPatcher.
This PR introduces in NanaZip FM a Detours hook of NtMapViewOfSection that inspects a mapped DLL's identity and denies the mapping if it belongs to a predefined list, which at the moment contains only ExplorerPatcher.
Also reenable dynamic code mitigation on main NanaZip FM thread.
Tested on Windows 11 with ExplorerPatcher installed.
Additional mitigations to follow.
