更新后， Win11 上编译 C++常用库被 Defender 报毒

[Thymolblue]

各位 V 友帮我看看是我中病毒了还是确实是误报

在今天更新完系统后，包括 opencv, zlib, eigen 在内的库均无法编译，全被 Defender 拦截了

下面是以我编译 zlib-1.3 为例

Environment

• MinGW 11.2.0
• CMake 3.24.2
• Windows 11 (23H2, 22631.2861)
• Security intelligence version(Defender): 1.403.485.0 (last update 2023.12.14)

Library

• zlib-1.3( https://www.zlib.net/zlib13.zip)

  SHA-256
  c561d09347f674f0d72692e7c75d9898919326c532aab7f8c07bb43b07efeb38
  

Command

C:/Qt/Tools/CMake_64/bin/cmake.exe -G "MinGW Makefiles" -D CMAKE_C_COMPILER=gcc -D CMAKE_CXX_COMPILER=g++ -D CMAKE_C_FLAGS_DEBUG=-O3 -D CMAKE_C_FLAGS_RELEASE=-O3 -D CMAKE_CXX_FLAGS_DEBUG=-O3 -D CMAKE_CXX_FLAGS_RELEASE=-O3 -D CMAKE_BUILD_TYPE=Debug -D CMAKE_PREFIX_PATH="C:/Work/dep/MinGW11.2.0/Debug;${CMAKE_PREFIX_PATH}" -D CMAKE_INSTALL_PREFIX="C:/Work/dep/MinGW11.2.0/Debug/zlib-1.3" -B . -S ..

C:/Qt/Tools/CMake_64/bin/cmake.exe --build .

C:/Qt/Tools/CMake_64/bin/cmake.exe --install .

1. 建议综合多个杀软的结果来确定是否误报，具体操作是将报毒的文件上传到 [VirusTotal]( https://www.virustotal.com)
2. 建议禁用 Defender 以**大幅加快**编译速度，随便换个杀软性能都比 Defender 好很多

[miaomiao888]

不确定你的情况
但最近 Defender 似乎更新了病毒库导致一些误报，反正我有个软件是突然收到误报反馈。
Defender 很恶心，加白除了添加排除路径，还得关实时保护，否则软件运行后照样扫内存强行删除。
同样建议换，这坨东西一点都不专业。

把工具包和源码路径加到排除的目录

[chilledheart]

MinGW 的不清楚，我用 msvc 编译的上传再下载就当病毒了，自己都觉得很惊奇。

@chilledheart
确实 defender 的报毒很迷，而且连操作时间都不给

[sariya]

放排除列表吧，可能是一些动态生成 exe 的操作触发了误报

[klosw]

为啥不把项目目录在 Defender 中排除呢

[Thymolblue]

@klosw 被 defender 报毒是在 14 号更新后发生的，主要是不确定是否真的中毒了

[Thymolblue]

来结一下题，就是微软的误报，把 CMake 更新到 3.27 之后就能成功编译了。
