But if you’re looking for comprehensive internet security protection, and you don’t want to fall victim to things like ransomware or advanced malware attacks, you’ll need to invest in a paid antivirus. If you only need simple scanning and basic malware protection, you only need a free antivirus. I’ve researched and tested all major antivirus software designed for Macs to find the best 100% free products available to help you stay protected. That’s why it’s important that you find a product that has been extensively tested and that is guaranteed to offer at least a basic level of protection without compromising your cybersecurity. And there are also free antiviruses that are actually spyware in disguise, designed to steal user data. I tested every single free Mac antivirus program on the market, looking for software that could provide decent anti-malware protection for macOS without forcing users to upgrade to the premium version. Most antivirus brands that offer free products usually make you “pay” with intrusive ads, limited features, and serious vulnerabilities that leave you and your Mac unsecured.
