Does Kali Linux OS actually have malware?

I downloaded the Kali Linux 64 bit from TechSpot, and I know that it has a 100% safe download. But I ran it though Windows Security and it found 77 threats. Most of them I know are just part of Linux because there classified as Hack Tool. But there are several Trojan Horses and ransomware. I just want to be sure it's safe to use before I remove Windows and install it as the OS on my second laptop
