How to Scan Your Mac for Viruses and Malware

You might already know that macOS comes with built-in security features like XProtect and Gatekeeper. For most people, these are actually good enough to keep your Mac safe.

If you’re curious, Apple has some official docs explaining how these work:

How does XProtect work?

XProtect runs automatically in the background. There’s nothing you need to open or click. It quietly checks files against known malware and blocks anything suspicious.

So no, you don’t need to “run” it manually.

The only thing you should do is make sure automatic security updates are turned on, and here is how to do it:

1. Press Command (\⌘) + Space to open a Finder search window.

2. Type and open System Settings.

3. Go to General > Software Updates.

4. Tap the ⓘ icon behind Security updates.

5. Make sure “Install system data files and security updates” is checked.

Do you need extra virus protection?

For most people, macOS built-in protection is enough.

That said, if you store important data or download files from the internet often, using an extra layer of protection isn’t a bad idea.

Think of it like this: no security system is perfect. Using more than one tool just reduces the chance of something slipping through.

Also, threats are getting more advanced over time. New types of malware show up regularly, so relying on just one layer of protection may not always be enough.

Malwarebytes is a well-known and reliable tool. The free version works great for occasional scans and cleaning up any malware it finds.

You don’t have to pay unless you want extra features like real-time protection or VPN.

FAQs

Do Macs get viruses?

Yes, unfortunately, macs aren’t immune. They can still get viruses and other types of malware, just less frequently than Windows PCs.

Viruses are relatively rare, but adware and shady apps are much more common, usually coming from suspicious downloads or fake software.

If your Mac starts feeling slow or acting weird, it’s worth checking your Activity Monitor, Login items and Browser extensions.

For scanning, the free version of Malwarebytes works well.

And honestly, installing a good ad blocker and being cautious online will already protect you from most problems.

Should I get third-party antivirus software?

As mentioned earlier, macOS already has solid built-in protection, and for many users, that’s enough.

But if you want extra peace of mind, adding a trusted tool like Malwarebytes is a simple way to add another layer of security.

How to protect your Mac from malware?

For most people, the built-in tools are enough, as long as you follow some basic habits:

Keep your system up to date
Avoid downloading apps from unknown sources
Don’t click on suspicious links
Use an ad blocker

More advanced users might separate risky activities into different user accounts or use virtual machines, but that’s optional.

Should I run antivirus all the time?

Personally, I don’t run antivirus all the time on my Mac. Instead, I scan it occasionally to make sure everything is clean.

That said, it’s a good idea to run a scan if you’ve downloaded files from unfamiliar websites or clicked on something suspicious.
