When it comes to Mac computers, many users believe they’re immune to viruses, but this isn’t the case. Even Macs can be infected. If your Mac is acting up, you might have a virus.
This article will provide a guide to swiftly get rid of virus on Mac. We’ll cover everything from the signs of infection to the use of antivirus software and preventative measures.
Identifying Common Mac Viruses and Malware

Mac malware can take many forms, like adware, which bombards you with ads; ransomware, which demands payment to unlock files; and Trojans, which disguise as legitimate software.
Keyloggers are stealthy, recording keystrokes to steal information. Look for unknown apps in your Applications folder and increased network activity from unknown processes in your Activity Monitor.

- Release the Shift key when you see the login window appear.
- Once logged in, you’ll be operating in Safe Mode, where Mac loads only essential system processes.
- Open your installed antivirus and run a full system scan.
- Remove any detected malware following the antivirus software’s instructions.
- Restart your Mac without holding any keys to leave Safe Mode.

The Importance of Regular Software Updates for Security
Regular software updates are crucial for Mac security because they often include patches for security vulnerabilities that have been discovered since the last update.
Hackers and malware creators exploit these vulnerabilities to gain unauthorized access to systems or to inject malicious software. Updating your Mac ensures you have the latest defenses.
Not updating leaves your system exposed to known attacks, which is why cyber security experts stress the importance of keeping software current and understanding how to get rid of Mac malware.
How to Spot and Avoid Phishing Attacks on Your Mac
Spot and avoid phishing attacks on your Mac by:

- Keeping your Mac’s operating system and browsers updated.
- Employing browser extensions that warn about suspicious websites.
- Securing powerful passwords for different accounts and enabling two-factor authentication.
- Regularly backing up data to recover in case of a phishing incident.
Setting Up a Standard User Account for Safer Browsing
To set up a standard user account for safer browsing on your Mac:
- Open System Preferences and select ‘Users & Groups.’
- Click the lock and enter your admin password.
- Press the plus sign to add a new user.
- Choose ‘Standard’ from the New Account dropdown menu.
- Fill in the user details and create a password.
- Log out of your admin account and log in with the new standard account for everyday use.
This limits the permissions for installing software and changing settings, reducing the risk of changes by malicious software.
Understanding the Gatekeeper Function in macOS for Better Protection
The Gatekeeper function in macOS provides better protection by controlling what apps can be installed on your Mac. To use it:
- Access System Preferences and select ‘Security & Privacy.’

- For extra security, click the lock icon at the bottom left to prevent changes without administrative authentication.
- If you need to open an app not recognized by Gatekeeper, right-click on the app and select ‘Open,’ which prompts for a manual override on a case-by-case basis.
Using it along with your knowledge about how to remove a virus from your Mac can effectively keep you safe.
