I was also convinced not to need it but after having received a very nasty letter from my internet provider (caused by an old Windows notebook I was trying to bring to life and must have received an infection during my procedures) I decided to be more cautious.I have never used it on a Mac, it seems more people do now. So I am wondering how many people use antivirus software (like Malwarebytes) now? Please vote, thanks!
I usually run Windows. I'm typing this on a Win 10 system. I ensure that there is working, properly set up, antimalware software running on this, and all other, Windows systems I access. I do not _care_ if malware gets sent from a Mac or a Linux machine due to the people running those machines not having antimalware running. _They_ are not responsible for the operation of my Windows machines, _I_ am. The 'protect the Windows people' mindset is one I find particularly stupid.I was also convinced not to need it but after having received a very nasty letter from my internet provider (caused by an old Windows notebook I was trying to bring to life and must have received an infection during my procedures) I decided to be more cautious.
True, virus are usually made for Windows OS but you may send (not being aware) an infected file to someone running Windows... or a malware can leave your mac and enter the provider's network
"Adware Zap" did found and removed some minor non-dangerous nuisances (adwares) in my mac. A good small app.
However if you run a dual OS system including a Windows partition (as I do) and often move data from one OS to the other, to install a true antivirus application working in your MacOS like Eset or Symantec is IMHO not a very bad idea, although you can no doubt live without it if you are careful enough.
Curiously a well updated current Windows 10 does not necessarily need any longer additional antivirus applications as long as you leave the built-in "Defender" always in ON position, update it very often... and you do not visit dangerous web sites or download warez. Microsoft has done a good work to improve the fight with malware in their newest Windows 10 issues.
That an antivirus should make your mac run slower is often said but (without running -of course- any comparative speed workbench!) I have never noticed any such negative effect, so, if it happens, it must hardly be noticeable in normal mac environments.
Of course some antivirus applications have the bad habit to pop up at starting the macand nobody likes pop ups, but otherwise I can live with an antivirus... and am not afraid I could not entirely remove it one day if I wish to do so.
As mentioned, I have learned in a very unpleasant way that internet access puts the user under the authority of the web provider who can put him/her offline if the user is not careful enough.
However in my painful story with my provider I have no doubt that Windows(-Virus) was the cause of my sin, not MacOS!

I am of course no expert in cyber security.I usually run Windows. I'm typing this on a Win 10 system.

Note that Windows Defender is, at best, minimal protection. I use Kaspersky on my Windows systems. YMMV.
I very much doubt that people who buy a Mac and use in it some flavour of MacOS, do it just not to care too much about virus problems.If macOS needs an antivirus someday, we'll probably move to Windows. One of the main attractions to get a Mac is discharge us from the concern about viruses.
Linux is in general safe, but it's not as convenient as macOS, which has better hardware integration and a more polished GUI compared to most Linux window managers. But I was comparing to Windows ecosystem, which is Apple's main competitor.I very much doubt that people who buy a Mac and use in it some flavour of MacOS, do it just not to care too much about virus problems.
If that would be the only reason there are plenty of free of charge Linux OS one can choose, perfectly matching the hardware of any computer, even an old and cheap one.
You can download excellent free Office applications, free Gimp image manipulation and almost everything most non pros need for free.
Linux is usually as free of virus problems as MacOS usually is.
Still many people invest in Apple Macs and enjoy using them.
Therefore there must be other reasons besides the virus factor which explain that joy many computer users feel with Apple hard and software.

A very interesting point of view that many many thousands of computer users all over the world, mostly running some Windows OS, ignore but YOU KNOW.Anti-virus software makes your computer more susceptible to hackers. It’s is riddled with bugs for the bad guys to steal all your money.
I too use sophos . I think my problem was Facebook. I deleted my account about 4 months ago. Have not had a problem.I do ... just in case. I run Sophos AntiVirus Mac - it's free and i never even notice it running in background. Perfect win win situation. It occasionally quarantines an email with a virus so it does it's job. Try it.
