Re: [Warning]: New MacOS malware discovered named Atomic MacOS Stealer.
I was a Windows OS user in the past and often had problems when it was exposed to malware, then finally switched to macOS about ten years ago. Until now, I have never experienced being exposed to malware. But just in case, I had Bitdefender antivirus installed for a few years.
Antiviruses are good, but be sure to use the paid versions as free ones are much likely to be weak in protection, Also engineers that help less tech savvy people install operating system in their computers have the higher tendence of intentionally installing Porus software that can victimize their clients in the long run, so It is still safer if you can change the OS of your device by yourself without the involvement of a third party and be sure to use a paid license instead of a cracked version. By the way, the post you quoted is old (2023).
I used the Bitdefender Total Security paid version, which has a license for five devices and one account for a year. I have extended the duration several times by purchasing a new permit.
Using a free antivirus can be useful, but of course, the features are usually limited, and advertising is often added.
Meanwhile, if you use a cracked version of Antivirus, it is the same as increasing the risk of opening up the possibility of malware entering through the crack key.
