For years the belief circulated that Apple computers were immune to malware. However, 2025 data shows a different reality: Mac viruses and MacBook malware are on the rise, driven by growing cybercriminal interest in systems that were previously less targeted. Although macOS remains one of the most secure operating systems, protecting your Mac requires a combination of tools, good practices and advanced MacBook cybersecurity solutions.
Do viruses exist on Mac? What you need to know in 2025
Yes, they do. Although macOS includes native security measures, Mac viruses and other types of digital threats have evolved. According to reports from Malwarebytes and AV-TEST, in 2024 there was a 50% increase in new adware and trojan variants designed specifically for Apple users.
Attackers exploit vectors such as: applications downloaded outside the App Store, phishing emails with malicious links, and vulnerabilities in browsers or plugins.
Main cybersecurity threats in macOS
- Adware: floods the user with ads and slows down the system.
- Trojans: disguise themselves as legitimate apps to steal data.
- Spyware: monitors passwords, emails and online activity.
- Ransomware: blocks device access until a ransom is paid.
- Phishing: deceives users with fake pages imitating official services.
How to tell if your Mac is infected: most common signs
- Pop-up windows or constant adverts.
- Sudden slowness without apparent cause.
- Unknown apps in the Dock or Applications folder.
- Strange redirects when browsing the internet.
- Overheating or unusual resource consumption.
Antivirus for Mac: which ones are worth it?
From Setek Consultants we recommend: Jamf Protect, Mosyle EDR, and Hexnode EDR. These solutions reinforce Mac security against threats that native defences do not always block.
Native Apple tools to protect your Mac
- XProtect: automatic malware detection system.
- Gatekeeper: blocks apps from unverified developers.
- FileVault 2: encrypts the entire disk to protect information.
- Sandboxing: isolates processes to prevent malware spread.
- Activation Lock (Find My Mac): deters physical theft.
Good digital security practices in daily life
- Download apps only from the App Store or verified developers.
- Always keep macOS and all applications up to date.
- Use strong passwords and enable two-factor authentication.
- Avoid public Wi-Fi networks without a VPN.
- Make frequent backups with Time Machine or cloud solutions.
What to do if you think your Mac has been compromised
- Disconnect it from the internet to prevent data leaks.
- Scan the system with an updated Mac antivirus.
- Manually remove suspicious applications.
- Change the passwords of your main accounts.
- Consider reinstalling macOS from scratch if the infection persists.
- Contact a MacBook cybersecurity specialist for a professional review.
In 2025, Mac viruses and MacBook malware are a reality. Relying solely on built-in defences is no longer sufficient: you need to combine Apple antivirus, native macOS tools and solid digital security practices to keep your device protected against growing digital threats.
