You should begin with checking the security settings. They prevent a software to be installed or opened if it is not digitally signed or approved by Apple.

It’s possible to remove malware from a Mac or PC by running a scanner and taking steps to fix your web browser. Here’s our step-by-step guide to removing malware from your computer.

How to remove malware from a Mac

Step 1: Disconnect from the internet

Free Mac Malware Removal

Disconnecting from the internet will prevent more of your data from being sent to a malware server or the malware from spreading further. So stay offline as much as possible if you suspect that your computer has been infected. If you need to download a removal tool, disconnect after the download is complete and don’t connect again until you are sure that the malware has been removed.

Step 2: Enter safe mode

Safe mode, often referred to as safe boot, is a way to start your computer so that it performs checks and allows only the minimum required software and programs to load. If malware is set to load automatically, this will prevent the malware from doing so, making it easier to remove. To enter safe mode:

1. Start (or restart) your Mac, then immediately press and hold the Shift key. The Apple logo will appear on your display.
2. Release the Shift key when you see the login window (if you are asked to log in twice, learn more about what to do here).

Disclaimer: Avoid logging into accounts during malware removal

Be careful to not expose passwords though a copy-paste function or by clicking a ‘show password’ box if you suspect your computer has been infected. Keylogger viruses are a common component of malware, which run invisibly and are designed to capture your keystrokes. To avoid sharing your personally identifiable information, refrain from logging into sensitive accounts while your device is infected.

Step 3: Check your activity monitor for malicious applications

If you know that you’ve installed a suspicious update or application, close the application if it’s running. You can do so by using your activity monitor. This shows the processes that are running on your computer, so you can manage them and see how they affect your computer’s activity and performance.

Malware can take up resources on your computer, so check the CPU tab to see which applications are working the hardest. If you are able to find the suspicious application, you can close out of it through your activity monitor and then delete the application from the Finder menu. To check your activity monitor:

In Finder, click → Applications → Utilities → Activity Monitor → Select Application → Quit

How to help protect your devices from malware

Malware or viruses get on your computer in a handful of ways, so it’s a good idea for computer owners to develop good online habits to avoid an infection. Use our best practices below to help protect your computer:

How To Remove Malware From Mac

• Avoid suspicious emails, links, and websites. Sometimes malware or viruses are disguised as an image file, word processing document, or PDF that you open. Additionally, if you find a strange new file on your desktop, do not open it.
• Clear your downloads and empty your trash often. If you’ve deleted downloads or moved suspicious files to the trash, empty the trash immediately after.
• Create strong passwords. Once you’re sure the computer virus infection has been cleaned up, change all your passwords, using unique combinations of letters, numbers, and symbols. Don’t use words found in the dictionary since they can be cracked via a dictionary attack. To help create, manage, and securely store all your passwords, consider using a password manager.

Malware is a dangerous threat to the data that computer owners store on their PCs and Macs. New types of malware are being discovered frequently, and the profitable nature of some types of malware can make it especially attractive to cybercriminals around the globe. It’s important to exercise good online habits and understand the signs of a malware infection.

If you suspect your computer is infected, act as soon as possible to prevent the spread of malware and protect your personal information.
