Qubes won't warn me If my Dom0 got compromised

I’ve read a lot about qubes, but I can’t seem to find anything on how to know if my system has been compromised. If I use any Linux distribution or even Windows, I can install antivirus and it will notify me if I have Malware or Ransomware (Actually It should, but it won’t ). For qubes why I can’t receive any message or notification warn me to take my precautions. Is it true that Qubes cannot identify malware or ransomware? Why do you believe it will be difficult?
