You don’t have to pay for antivirus protection on a Mac. Several reputable security companies still offer genuinely free macOS apps in 2026, although what you get from them can vary quite a bit.
Avast is our best overall pick because its free Mac software includes real-time malware protection. Avira and AVG also provide always-on protection without requiring a subscription, while Bitdefender and Malwarebytes are better suited to occasional scans when you want a second opinion or suspect something has already gone wrong.
That difference is worth understanding before you install anything. Some free antivirus apps continuously monitor your Mac, while others wait for you to start a scan. Paid plans also tend to keep their more advanced web, ransomware, privacy, and VPN features behind a subscription.
Avast remains our favorite free antivirus for Mac largely because you can install it and let it get on with the job. The free version provides real-time malware protection rather than waiting for you to remember to run a scan.
Once it’s set up, Avast monitors your Mac for viruses and other malware in the background and receives automatic security updates. That makes it particularly easy to recommend to anyone who wants an extra security layer without having to think about it every time they download something. Avast supports both Intel and Apple silicon Macs.
You’re still getting the free version of a paid product, and Avast doesn’t hide that fact. Some of its more advanced ransomware, network, privacy, and browsing protections require a paid plan, and you’ll encounter upgrade prompts while using the app.
Those compromises don’t undermine the basic package, though. If your main priority is free antivirus that actively watches your Mac instead of sitting around until you open it, Avast is still the strongest all-around choice here.
Avira still earns a place here because its free Mac app combines real-time malware protection with a broader bundle of security and utility tools.
The antivirus itself supports quick, full, and custom scans, along with cloud-assisted threat detection. Avira also includes a password manager, junk cleaner, and VPN. That VPN is capped at 500MB of data per month, so it won’t replace a standalone VPN, but it can still be useful occasionally.
The bundle is the main reason to choose Avira. If you like the idea of getting several basic security and maintenance tools from one download, it offers more than most free antivirus apps.
There is one important caveat. Avira’s March 2026 AV-TEST result was weaker than the scores posted by Avast and AVG, so we wouldn’t rank it ahead of either of those products for pure malware protection right now. That doesn’t make the free package useless, but it does make the extras a bigger part of its appeal.
The app can also feel busier than a more focused antivirus, and several features point toward Avira’s paid products. If you’ll actually use the bundled tools, though, it remains a worthwhile free option.
AVG AntiVirus Free doesn’t try very hard to reinvent the antivirus app, and that’s part of its appeal. It gives you basic real-time malware protection without asking you to manage a collection of extra utilities.
The app can watch for viruses and other malware in the background, check potentially risky files, and keep its threat definitions updated automatically. Once everything is configured, there isn’t much you need to do.
AVG also performed extremely well in independent Mac testing in 2026. Its results closely track Avast’s, which isn’t especially surprising because both products are part of Gen Digital and share the same underlying Avast antivirus engine.
There’s still a paid product waiting in the wings. AVG reserves additional protections for AVG Internet Security and may offer trials of its premium software. If you accept one, check the billing terms carefully so a free antivirus experiment doesn’t quietly turn into another subscription.
AVG doesn’t have one killer feature that pushes it ahead of Avast. What it does have is a simple pitch: free, always-on malware protection without a lot of additional clutter.
Bitdefender Virus Scanner for Mac isn’t trying to replace a full antivirus suite. You open it when you want something checked, choose what to scan, and let Bitdefender take a look.
You can scan critical system locations, running apps, individual folders, or your entire Mac. Bitdefender also looks for Windows malware, which is handy if you share files with Windows users and don’t want to unknowingly pass something nasty along. Virus signatures are updated before scans, and detected files can be quarantined or removed.
The narrower approach works well if you’re comfortable relying on macOS’ built-in protections most of the time. Maybe you’ve downloaded a suspicious file, something on your Mac suddenly feels off, or you simply want another security engine to check things over. Bitdefender fits those situations without demanding much attention in between.
You won’t get continuous third-party monitoring from this free version. Bitdefender keeps its broader preventive Mac security features for its paid products.
That makes Virus Scanner less of a security guard and more of a very useful second opinion.
Malwarebytes Free is the one I’d reach for when a Mac has already started giving you reasons to be suspicious.
Its free version lets you run quick and custom scans to find and remove malware. Maybe your browser is behaving strangely, you installed something questionable, or another antivirus didn’t find anything and you’re still not convinced. If you’re already at that stage, our guide on how to check your Mac for viruses and malware walks through what to look for and what to do next.
The free version doesn’t continuously protect the Mac in the background. Real-time malware and web protection belong to Malwarebytes’ paid plans, so you shouldn’t treat the free app as a direct substitute for Avast, Avira, or AVG.
That limitation also keeps its role fairly clear. Malwarebytes can sit alongside macOS’ built-in security or another antivirus product until you actually need it. You don’t have to rebuild your entire security setup just to get a second scan.
Not everyone needs third-party antivirus because macOS already comes with a substantial set of security protections. If you want the broader basics first, we also have an explainer on what antivirus software is and how it works.
Apple uses several layers to keep malware out. Gatekeeper checks software downloaded from outside the App Store, notarization helps identify potentially malicious apps before they run, and XProtect works as Apple’s built-in antivirus technology for finding and removing known malware. Apple can update XProtect separately as new threats appear.
For someone who keeps macOS updated, sticks mainly to trusted downloads, and doesn’t click through every security warning that appears, that’s a strong starting point.
That doesn’t mean Macs are somehow immune. New threats still appear, including recent Mac malware that tried to trick users into surrendering their passwords. Third-party antivirus can add another layer if you regularly install software from around the web, work with files from lots of different sources, or simply prefer having another security company checking what reaches your Mac.
Free antivirus gives you some room to choose how far you want to go. Avast, Avira, and AVG can provide continuous protection, while Bitdefender or Malwarebytes can stay out of the way until you want another scan.
Avast is still the easiest recommendation for most people. Its free tier provides real-time malware protection, the core experience doesn’t require a subscription, and you can mostly leave it running in the background.
AVG is the strongest straightforward alternative, while Avira makes more sense if you want extra utilities alongside antivirus protection and are comfortable with its weaker recent independent test result. Bitdefender is better suited to occasional scanning, and Malwarebytes earns its place when finding or removing something suspicious is the priority.
There’s also no prize for installing every antivirus you can find. One app providing real-time protection, perhaps backed up by an on-demand scanner when you want a second opinion, is a far more sensible setup.
Yes, as long as you get it directly from a reputable security company or trusted app store. The bigger compromise with free antivirus usually isn’t safety. It’s that some features are reserved for paying customers.
For plenty of Mac owners, it can be. macOS already includes Gatekeeper, notarization, XProtect, and other protections designed to block and remove malware.
A third-party antivirus adds another layer and may be worthwhile if you regularly download software from less predictable sources or simply want an additional security engine watching your Mac.
Free antivirus generally concentrates on malware detection and basic protection. Some products provide real-time monitoring, while others stick to scans you start yourself.
Paid plans tend to bundle in broader web protection, ransomware defenses, VPNs, privacy features, scam detection, and support for multiple devices.
You can pair an on-demand scanner such as Malwarebytes Free or Bitdefender Virus Scanner with another security product without much trouble.
Running two antivirus apps that both monitor everything in real time is harder to justify. Their protections can overlap, use extra resources, and sometimes get in each other’s way. One always-on antivirus is generally enough.
Anthropic has officially filed to go public, and buried inside its S-1 is a blunt warning about the technology at the center of its business. The maker of Claude AI says advanced AI could cause everything from large-scale cyberattacks and geopolitical instability to catastrophic or even existential risks for humanity.
The warnings take up a surprisingly large part of the filing. Axios notes that more than 90 pages, or roughly a third of the prospectus, focus on risk factors. Many of them warn about what could happen as AI systems become more capable and autonomous.
AI giants have a growing autonomy problem on their hands. A new Axios report has revealed that Anthropic's Claude recently accessed publicly available Georgia vote count without human authorization, sparking fresh concerns about AI security ahead of the upcoming midterm elections.
