Yes, as discussed previously: there is no absolute security. And correct, if you are striving for 100% security don't use a computer.
Yes, that is the key. I disagree with the false claim that users must have antivirus/anti-malware apps installed in order to keep a Mac safe from malware. I also disagree with the claim that you should never install such an app. My claim has always been that you can use such apps, but you don't need to use them to keep a Mac malware-free, as long as you practice safe computing, which you should do with or without such apps.
Antivirus or anti/malware apps will not protect you against some future zero-day threat, but practicing safe computing will.
As has been repeated countless times, Macs can get viruses and other forms of malware. They do get other forms of malware, but they don't get viruses, because none have ever existed in the wild that run on macOS/OS X.
If you run an antivirus app in the absence of safe computing practices, you say that it gives you peace of mind, but what you're really getting is a false sense of security that can bite you at some point in the future. If you really want to do people a service, teach and promote safe computing, with or without your recommendation for anti-malware apps.
That article does not refer to a virus, but a Trojan, which cannot infect your Mac unless you first install it. In addition, not every antivirus/anti-malware app will detect this Trojan, so some people who follow the mantra of installing an antivirus app instead of practicing safe computing will be disappointed when they find their Macs infected because they unwittingly installed a Trojan and their particular AV app didn't detect it.
Where is the point in using AV that neither detects nor protects but instead introduced new threat vectors?
This question has been answered already. Now we are just going in circles.
Of _course_ this applies to Windows malware. It's called a zero-day, and it happens with depressing frequency, and unless and until new antimalware detection libraries come out with the ability to see it, existing Windows antimalware can do little or nothing to stop it.
These questions are like a dog chasing it's own tail while looking for something to play with.
You weren't part of the Mac AV debate before but many of these questions were hashed and rehashed for a long time before you entered into the conversation. At one point it devolved into a debate over semantics about what a virus is or isn't, the differences between malware, trojans, viruses... etc.. It's been the same ole questions and answers in these threads for a while. You can go back and re-read this and other related threads to gain a better perspective.
That’s like saying the difference between tractors, submarines, airplanes, buses, bicycles and cars is just semantics. They’re all submarines, right?
I'll take some percentage of protection on my Mac over no percentage of protection. You can go naked and run with the the sheep if you want. No one is forcing you to use Mac AV/security software.
Correction: You take the bogus impression of increased protection with actually decreased protection vs system level protection. Notice the difference.
Practicing safe computing provides a much higher level of protection than running any A/V app, some of which can actually increase your risk of infection. You're promoting a lower level of protection than those of us who know better.
An even better strategy is to practice safe computing AND use Mac AV/Security software.
My Mac AV software (free) has been blocking infected files and bad web links for years. I'm not sure how you equate that to decreased protection... and YES I want the potential Windows infections blocked as well.
That depends on which AV app you use. For most, adding an AV app to safe computing adds no additional protection, but it doesn't hurt (except perhaps performance). For a few AV apps, they actually decrease protection and increase risk.
I've been successfully avoiding infected files for 10+ years with no AV software, by just using a bit of common sense. My adblockers take care of unwanted stuff on websites.
Checking the false positive rate vs the actual threat detection rate is revealing. Just check it. Plus AV - in particular when running in the background at all times scanning - opens an additional attack vector.
These things you're talking about apply to Windows systems as well and many people run Windows without AV software for years without getting any infections. So what's your point? If you don't want to use Mac security software then don't.
Those points are true also for Windows systems... false positives occur, addition attack vectors are exposed (as happened in recent past with built in Windows Defender being used as a method of attack) and it can give you a false sense of protection... yes... true for Windows as well... and many people run Windows without security software... they use common sense and don't seem to get infections. Go ahead and don't use Mac security software if that makes you feel safer.
Point being: Installing AVs actually increases the attack surface and therefore the likelihood you catch anything.
I don't understand that either... on new Macs the MacOS firewall is disabled by default?
Using a USB drive, downloading email, connecting to the internet, using a web browser and installing an app on your Mac that accesses the internet increases the attack surface too... If you want perfect Mac security just leave your Mac powered off.
I sleep well at night knowing I have Mac security software installed. You on the other hand would probably stay awake late at night... paranoid and staring at the ceiling if you had Mac security software installed... So for peace of mind you probably shouldn't install any on your Macs... and at least then you won't need to worry about those added attack vectors that you were referring to.
If it's AV snakeoil at least it's free AV snakeoil.
