I saw that there are many discussions on the topic: “Macos does not need anti-virus or sotware firewall“.
It is mostly true. The architecture of the macOS operating system is much less permissive than Windows, regarding the installation of executable applications without the user's consent. About the application installation restrictions on macOS, and especially on Sierra, we have discussed in the past. In the security settings, there are quite accurate options, which give the user control over the sources from which a program is downloaded and installed.

As can be seen in the screen above, by default applications can only be installed from App Store or from the developers (verified developers).
However, we know that it is not a 100% safe system and at any time it can happen that an application can infiltrate the system malware. Malware, I said. Here is another discussion. Many users confuse malware with antivirus. The difference between the two terms is like the difference between a bag and an orange. Being the bag “malware“, and the orange being the virus. Therefore, the term malware refers to both virus as well as atworms, trojan horses, ransomware, spyware, Adware, scareware, and malicious software.
For the macOS user, the probability of choosing a virus is very small, but with a Adware ormalicious softwareis not excluded.
In this sense, it is good to use a periodic (if not permanent) Anti-Malware program, capable of quickly and efficiently scanning important files in the system.
Malwarebytes Ani-Malware is a simple and free solution through which you can quickly check your system for worms, trojan horses, ransomware, spyware, adware, scareware and malicious software.

2. Install the application. Dear & Drop in the folder Applications.

3. Rulati Malwarebytes Ani-Malware.

4. Wait for it to finish scanning and show you the final result. The scan report.
After this scan you can uninstall the application.
Our advice is to always have the firewall activated and to periodically perform an ani-malware scan of macOS.
There are many less sites “orthodox” which offers antivirus solutions for macOS. Some even simulate a live scan of the system and notify you through various alerts that you have N* viruses on your Mac. Ignore these sites and look for safe solutions.
