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
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:
- Start (or restart) your Mac, then immediately press and hold the Shift key. The Apple logo will appear on your display.
- 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
Step 4: Run a malware scanner
Fortunately, malware scanners can remove most standard infections. It’s important to keep in mind that if you already have an antivirus program active on your computer, you should use a different scanner for this malware check since your current antivirus software may not detect the malware initially. If you believe your computer is infected, we recommend downloading an on-demand scanner from a reliable source and then installing and running security software which provides protection against existing and emerging malware, including ransomware and viruses.
Step 5: Verify your browser’s homepage
It’s common for malware to modify your web browser’s homepage to re-infect your Mac. Check your homepage and connection settings using the steps below for common browsers. Note that you will need to connect your computer to the internet to complete the following steps.
To verify your homepage on Chrome:
- In the top right corner of your Chrome browser, click More → Settings.
- Select the dropdown menu in the “Search engine” section.
- Verify your default homepage.
To verify your homepage on Safari:
- In the top left corner of your screen, select Safari → Preferences → General.
- Next to “New windows open with” and “New tabs open with,” select Homepage.
- Next to “Homepage,” you will verify your default homepage.
Step 6: Clear your cache
After you’ve verified your homepage setting, you should clear your browser’s cache. This is a temporary storage location on your computer where data is saved so your browser doesn’t need to download it each time. Follow these steps below to learn how to clear your cache for Chrome and Safari.
To clear your cache on Chrome:
Select Chrome → History → Clear Browsing Data → Time Range → All Time → Clear Data.
To clear your cache on Safari:
Select Safari → Preferences → Privacy → Manage Website Data → Remove All.

What if malware removal is unsuccessful?
If malware removal is unsuccessful, sometimes the only way to be sure your computer is free of malware is to entirely reinstall the operating system and your applications or programs from scratch.

How to tell if your device has been infected with malware
Some of the tell-tale signs of your device being infected with malware include:
- Changes in your device behavior: for example, unusual ads or pop-up windows may begin to appear, even when you’re not surfing the web.
- Your device may begin to run more slowly.
- Your device may suddenly lack storage space.
- Your browser behavior or homepage appearance may change.
- Ads may pop up featuring inappropriate content and flashing colors. They may also block whatever content you’re trying to view.
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:
- 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.
