My main PC is a windows PC (mainly for video games and music production). I also have a Macbook for my work as a (currently) Lead Systems Automation Engineer for a large global company (14 years in the industry, 3.5 of those was me “taking a break” and going into Infosec specifically to first do endpoint/end-user security, then moving into container and cloud security) a personal Macbook, as well as a few Linux laptops I use to write code and do other tech-related things because I prefer MacOS and Linux for that kind of work. I’m well-exposed to most operating systems and have a working knowledge of how security works, both in a professional setting as well as a personal one.
I mention BonziBuddy and search bars because they’re funny and to illustrate a simple point. The reality is that browser hijackers still very much exist (though they’re not as prevalent as they used to be because browsers themselves have become more resilient over the years - nowadays, they’re usually found in add-ons/extensions because its easier to fly under the radar that way).
For all the shady shit I’ve done on all of the above platforms, I’ve never had an issue. Specifically in Windows, Defender - which is still the de facto/standard security tool that comes bundled with Windows under the Windows Security tool suite - has not once flagged malware for me. I’ve found it with Avast and BitDefender, but Windows Defender simply isn’t great for the things I do.
I also run ClamAV on the Macbook for ad-hoc scanning of things I download prior to running them. Why? Because I’m not a negligent user and I do at least the bare minimum in regards to good security practices.
In every one of the above cases/operating systems/platforms, there is always some kind of security tooling or framework involved (whether that’s ClamAV on Mac, BitDefender or ClamAV or MalwareBytes or whatever on Windows, SELinux or AppArmor or ClamAV on Linux) that can and should be leveraged if you really want to be “safe.”
In the case of AMOS and Macs, users are purposely bypassing Gatekeeper and proceeding without knowing wtf they’re installing. As soon as Gatekeeper pops up like that, you should be on alert unless you know the software you’re installing isn’t signed, trust the source, and are willing to codesign it yourself.
You, on the other hand, clearly seem to have some kind of gripe against Macs (based off of your comments in this now far-too-long comment thread) and that kind of weird quasi-religious brand loyalty (or hatred) is a thing I’ll never understand.
The fact that you’re out on a public forum, spewing bad info/misinformation really says everything. Not that you care, but I’d have respected you more if you just admitted you were wrong and misread the bit about the Google ads. Instead, you decided to be confidently dumb and jump from hill to hill, prepared to die on each one of them.
