Most positive reviews mentioned the cases when the product was able to catch a virus or malware. Since most people usually leave reviews when they extremely happy or extremely unhappy with the product, the rating is impressive. At the moment of writing, there were 123 reviews with an average rating of 4.8. The company displays reviews on its main site. The best thing is it still has a free version. In 2015 Malwarebytes, a software company from California acquired AdwareMedic and rebranded it as Malwarebytes Anti-Malware for Mac. The product was a donationware developed by Thomas Reed. The story of Malwarebytes for Mac started when it was called AdwareMedic. There is also a Windows version, but I have no opinion about it.
In this article, I would only cover Malwarebytes for Mac. While I have never found any malware on those occasions, I do know how Malwarebytes works and can help you decide whether you need it or not and whether it is worth paying for. One thing I learned is that when their tech support suspects a possibility of a virus on your Mac, they usually suggest downloading and running free Malwarebytes. In the past, I contacted Apple multiple times.
