Was there any problem with 7z some years ago? I feel like I've been actively avoiding it for having the feeling that I've read something bad about it, but I can't remember what. But I could've mixed it with something else. It sometimes happens to me.
Ah, I think I might remember a couple RCE they had... [0]
So for Windows use I then started to recommend a fork called NanaZip [1] that enabled some Windows security features (CFG, CET, Package Integrity Check...) and added support for additional formats that other forks already had [2] [3].
