Can a MacBook Get a Virus? Here’s How to Protect Yours

Unfortunately, for many MacBook device owners, there is an age-old and common misconception that Apple Macs can’t get viruses. This belief can leave devices vulnerable to cyber threats. Although Apple’s macOS has built-in virus protection, it is important to remember that no system is entirely immune to cyberattacks. 

With this in mind, taking proactive measures to protect your digital data is something to take seriously. Here at My Computer Works, we’re committed to helping you understand how to protect your MacBook from viruses and malware, detect threats, and maintain optimal security. To help you do this, we have provided you with a detailed blog from our experts.

Can a Mac Get a Virus Even with Built-In Protection?

The short answer is yes. Macs can become infected with viruses. Even with security tools such as Gatekeeper, XProtect, and System Integrity Protection (SIP), no security software can grant your device complete immunity from cyber attacks. 

Hackers and cybercriminals develop new strategies every day designed against Mac owners, including adware, trojans, ransomware, and phishing scams. The more sophisticated the threats, the less you can rely on built-in security alone. 

That’s why it’s always a good question to ask: “Can I scan my Mac for malware?” You will be happy to know you can, but only with the correct tools and techniques, which we can show you at My Computer Works.

Built-In macOS Antivirus Software: Benefits and Limitations

Apple’s security features provide some protection but are not infallible, so let’s examine the advantages and disadvantages of Mac anti-malware capabilities.

Benefits of Built-In macOS Antivirus Features

• XProtect: Automatically scans and blocks detected malware.
• Gatekeeper: Prevents unapproved programs from being run.
• System Integrity Protection (SIP): Protects critical system files.
• Periodical updates: Apple periodically updates macOS to address vulnerabilities.

Limitations of Built-In macOS Antivirus Features

• Minimal real-time danger detection and eradication.
• They can miss new and zero-day threats.
• Does not have sophisticated anti-ransomware protection.

These limitations require understanding how to safeguard Macs against viruses and utilizing additional security tools in addition to the device’s built-in tools.

Signs Your Mac Might Be Infected with a Virus

Worried and wondering, “How can I understand if my MacBook is contaminated?” To answer this, if any of the following symptoms arise, your MacBook is likely infected:

• Slow performance: Sluggish performance or high temperature can imply rogue background processes.
• Surprise pop-ups: Overwhelming advertisements or baseless security alerts can signal malware.
• Unauthorized programs or add-ins: Unexpected programs appearing unrequested indicate an issue.
• Redirects in a browser: Frequent redirects to shady websites indicate malware activity.
• Random crashes: Frequent crashes can result from corrupt files and/or malware.

Once you notice such symptoms, a computer virus scan is essential for detecting and fixing a problem in its early stages.
