As a Mac user, you’re likely aware of the importance of protecting your device from viruses and malware. While Macs are generally considered to be more secure than PCs, they’re not immune to threats. In fact, the increasing popularity of Macs has made them a more attractive target for cybercriminals. In this article, we’ll explore the ways to check if your Mac has viruses and provide guidance on how to remove them.
Why Do Macs Need Virus Protection?
It’s a common misconception that Macs don’t get viruses. While it’s true that Macs are less vulnerable to viruses than PCs, they’re not completely safe. The rise of malware and other types of malicious software has made it essential for Mac users to take proactive steps to protect their devices.
There are several reasons why Macs need virus protection:
- Growth in malware attacks: In recent years, there has been a significant increase in malware attacks targeting Macs. Cybercriminals are constantly evolving their tactics, making it essential to stay vigilant.
- Increased exposure: As more people use Macs, the potential attack surface expands. This means that Mac users are more likely to encounter malware and viruses.
- Rising popularity: Macs are becoming increasingly popular, making them a more attractive target for cybercriminals.
Signs Your Mac Might Have A Virus
Before we dive into the methods for checking for viruses, it’s essential to understand the signs that indicate your Mac might be infected. Keep an eye out for the following:
Suspicious behavior:
- Unusual pop-ups or ads
- Slow performance or crashes
- Unexplained changes to settings or files
- Increased network activity
- Battery drain or overheating
Weird symptoms:
- Unfamiliar apps or programs running in the background

How To Check For Viruses On Your Mac
Now that we’ve covered the signs of a potential infection, let’s explore the ways to check for viruses on your Mac.
Use Built-in Tools
MacOS comes with built-in tools that can help detect and remove malware. Here are a few options:
- XProtect: This is a built-in malware scanner that checks for known malware and viruses. While it’s not a comprehensive solution, it’s a good starting point.
- Gatekeeper: This feature helps protect your Mac from installing malicious apps by controlling which apps can be installed.
- Activity Monitor: This tool allows you to monitor system processes and detect any suspicious activity.
Run A Virus Scan With Anti-Virus Software
While built-in tools are helpful, they might not detect all types of malware. That’s where anti-virus software comes in. There are many reputable options available, including:
- Avast
- Norton Antivirus
- Kaspersky
- Malwarebytes
Remember to:
- Choose a reputable anti-virus software
- Keep the software up-to-date
- Run regular scans
Check For Malware In System Preferences
Sometimes, malware can disguise itself as a legitimate app or system process. To check for malware in System Preferences, follow these steps:
- Go to System Preferences > Users & Groups
- Click on the “Login Items” tab
- Look for any suspicious or unknown apps
- Remove any apps that you don’t recognize or trust
