You forgot to check the .exe files. Ofc the .zip THEMSELVES are safe (not including what's inside), it's just used for compression. Anyways, I might be saying nonsense, I don't know how virustotal and these other vendors work, I don't know if they actually can scan what's inside zip files, but I extracted it and scanned the files individually and it said it was malware (yes I'm aware its only 2/69 but better safe than sorry). Anyways, once again, I don't really know what I'm talking about, I might be completely off, but I would just restate common sense and just say if something feels off, it probably is off. (do what you want i'm not an expert)
