Chapter in this post:
Antivirus software on the Mac or anti-malware apps on macOS are not required. In this post I would like to show you why this is the case and how I have been using Apple computers for over 20 years without even having a virus or trojan. I would also like to refute the rumor that you can do anything with an antivirus program on your computer and no longer have to think about possible dangers. Many examples - especially from the Windows and Android sectors - show that an AV app does not prevent infection, but at best can detect it. If you're lucky, she'll bring treatment tools too.
No antivirus software can protect a computer from threats 100%. Although it can warn of downloaded files, websites and other access or changes, as these can be potentially harmful. However, it is the user himself who ultimately decides whether the program should be executed, the website should be called up or access should be allowed. And it is not uncommon for impatience and ignorance to come together, an error can quickly occur and the malware is already installed. Then the AV app might still be able to do that Virus, the Trojans, which detect adware or similar malware, possibly even quarantine them. However, in the case of modern, sophisticated attacks, not all elements are removed.
Ergo: Antivirus software - no matter on which system from macOS to Windows and Linux to iOS, Android and others - does not really make sense. At most if there is already an infestation, but otherwise common sense is required when dealing with the computer.
Malware, its detection and combating as well as the emergence of new malware - this is a constant cycle. In the beginning there are the new viruses, Trojans, ransomware programs and the like. When they are detected, not only are anti-virus programs adapted to them (after they have failed and already allowed the infection on some computers), the sources of distribution (websites, programs, e-mails) are switched off and other countermeasures are taken. In the end, the AV people announce that their program now helps against Virus X and Trojan Y, but do not say that these dangers are no longer current. New, still unknown programs and scripts are in the works. And the cycle starts all over again.
As early as 2014, Symantec (the program forge behind "Norton Antivirus") recognized that antivirus software is basically useless and no longer relevant for the market. At that time, the Vice President for Computer Security at Symantec announced to the Wall Street Journal that antivirus software " dead ”. You can read the story from 5 years ago at heise and at Golem.
It has long been said that you don't need virus protection on an Apple Mac - mainly because hackers, malware programmers and ransomware blackmailers concentrate on the numerically superior Windows users. But even today, at a time when Apple Mac, iMac, Mac mini, MacBook and Co. are in greater demand, there is no need for antivirus software under macOS. With its proprietary system, Apple ensures that known dangers can be counteracted quickly with an update. This also applies to iOS on the iPhone, iPad and iPod Touch. In contrast to Android, where updates - if they appear at all - take weeks due to the open system of some manufacturers.
“A computer is only as smart as the person sitting in front of it.” - that is an old and not insignificant wisdom. Because if you are aware that unsolicited mail attachments, Programs loaded from software portals with installers and links in e-mails that appear insecure should not be opened, life is a bit calmer. When in doubt, every app and every file on the computer should be questioned. Here is a brief overview of things to look out for:
|Did I create the file myself / saved it on the hard drive?||Okay good.||If no reliable source can be determined: delete.|
|Do I know the sender of the email with the attachment or have I actively requested it?||Mail and attachment can be opened.||Delete and preferably mark it as spam right away.|
|Does the app come from the App Store?||Wonderful.||Then hopefully it comes directly from the developer, who does not ask for a PW during installation.|
|Should an app be installed via the installer, which asks for the admin password?||Don't install, delete.||See app store question.|
|Do I make regular backups, e.g. B. with Time Machine?||Very good, then accidentally deleted data or the entire system can be restored.||Why not?|
A little tip on the subject of e-mails and phishing: Google has released a phishing quiz that can help you find out more Phishing e-mails can safely examine for clues. Among other things in the Weekly news for week 4 I have already reported about it. You will also find the quiz, in which you learn to discover false senders, links, attachments, etc. with this link.
And if you're wondering which hard drive to use for your Time Machine backup, I have here is the appropriate contribution.
There is no need to install antivirus software on Apple Mac. On the one hand, because it doesn't really bring anything. On the other hand, because Apple quickly protects the macOS operating system from emerging threats. In addition, AV apps themselves are a source of danger as they open pretty much all files, programs and scripts for analysis. This means that they offer an enormous target area for those digital pieces that you actually don't want to open. If you want to protect yourself from viruses, Trojans and the like, you should simply work with care and a little brainpower on the Mac. It's also been the path I've been walking for over 20 years, and so far I haven't had a single virus on my Mac.
