Stay safe from virus and malware activity on your Macintosh with these simple tips.
The most common names for this malware are MacDefender, MacProtector and MacSecurity. Apple released a free software update (Security Update 2011-003) that will automatically find and remove Mac Defender malware and its known variants. To get rid of malware, you need to purchase the Premium version of Combo Cleaner. Open the app from your Launchpad and let it run the update of malware signature database to make sure it can identify the latest threats. Click the Start Combo Scan button to check your Mac for malicious activity as well as performance issues.
Do you think your Mac has been infected by malware or a virus? It’s always possible, and here’s some ways to check.
Is it a virus? Is it malware?
First of all, don’t blame every single problem on malware or a virus. Many problems on the Mac appear to be virus related, but, actually are system related. If you’re not surfing underground sites or downloading software from places you shouldn’t, you shouldn’t have any virus or malware activity. In the off chance that you do get a virus or malware, here are some basic things you should do to get rid of the malware or virus on your Mac.
Let’s start with the browser.
On the Macintosh, you have a few choices for web browsers. The big three browsers that most people use are Google Chrome, Safari, and Firefox. Of these particular browsers, we prefer Google Chrome as our day-to-day browser. Google chrome for Mac is a fairly lightweight browser, has great security controls, and doesn’t seem to have the issues that the other browsers tend to have. Another great feature of Google Chrome is that it has Adobe Flash built right into it. This means you’re not hounded by the constant warnings to upgrade Adobe Flash. This is not to say Safari and Firefox are not safe, we just have a better track record with Google Chrome across-the-board. It’s wise to be careful what extensions you do load into Google Chrome. Only stick to known good browser extensions that are featured on the Google app store. if you do need to stick to using Safari as your daily web browser, you should turn off the extensions. Extensions and toolbars are a common way for malware and viruses to get into your Mac.
Use free Malware and Virus checking software
The best free software we have found to detect malware on your Mac is Malwarebytes. This software is remarkably easy-to-use, and can be run once or twice a week to check for any malware on your Macintosh based computer. We’ve been surprised a few times to find that we actually did have malware and the software has found it and deleted it every single time. This software doesn’t run automatically; you will have to run it by yourself once in a while. Another great piece of software we have found the check for viruses and malware on a Mac is from the company Sophos. This free software does run continually on the Macintosh and is also a good, lightweight piece of software for checking viruses and malware on a Mac. Apple can also detect and defeat certain malware from their end which is built into the Macintosh operating system. This is obviously not the best option because you have no control over what it finds and what it gets rid of.

Backing up your data is a wise move
With good data backups, a good portion of malware and viruses shouldn’t affect your data. Even better, have multiple backup options so your main data backup doesn’t get infected. We prefer multiple hard drives, and Google Drive as our backup options. Apple provides the Time Machine software that can back up every single Mac for free. All you have to do is provide an external hard drive for this option to work.
Be incognito whenever possible
Most browsers today offer an incognito mode, Or stealth mode, which hides your browsing activities. If there are sensitive sites you travel to, using one of the stealth modes may help limit the malware and virus activity on your Mac. The stealth mode can stop tracking and automatically turn off cookies on these sites as you visit them, which aids in your protection.
Stay away from filesharing and torrent sites
A lot of virus and malware activity on a Mac comes from filesharing and torrent sites. You should limit access to the sites if at all possible, especially if other family members are using the Mac. A good option in this case is to use a DNS filtering service such as OpenDNS to stop people in your household from accessing these and other dangerous sites.
Everyone should not be an administrator on the Mac
If your Mac has multiple users, and all them are set up as a administrators, this is not a good situation. This simply means that anybody using the Macintosh has full privileges on the Mac. They would actually be able to install any piece of software, including malware, that they deemed fit. Changing these users to standard users is a great way to bypass this problem. By making them standard users, they don’t have the privileges that an administrator would have. Therefore, they would not be able to make any changes on the system at all. By teaching these users good browsing habits, you should be able to limit the amount of malware and virus activity on your Mac.

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.
How to remove malware from a PC

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