Learn how to get rid of adware on Mac

Macs are susceptible to malware, and one common threat is adware. Most of the time, it is simply annoying, but some versions of ad software also contain hidden viruses, posing a serious risk to your Mac and the data it contains. Fortunately, it is not difficult to remove it. You can do it either manually via your browser and your system files or with a cleaner tool like CleanMyMac X. We’ll take you through each of these methods to help you get rid of adware on your Mac for good.

What is adware?

Adware is malicious software responsible for those unwanted pop-up ads you see when you’re online. It may turn your browsing into complete chaos, opening pages you didn’t intend to visit and showing ads non-stop, and may sell your data to third parties.

How to check if Mac has adware?

First, check if your Mac has any of the following symptoms:

You see pop-ups and banners that advertise fake updates or software on websites and in search results.
Your browser settings have been changed without your knowledge, and unwanted toolbars appear.
You now experience browser redirects — links that you click in search results take you to a different website.
Mac performance seems much slower than usual.

Besides, you can open the developer mode in your browser and check the code. This string of code is an example of an adware program on Mac. As you can see in the third line, it “downloads offers” for the user, which will look like intrusive banners and pop-ups to you.

Malware distribution methods

The ways malware gets into our Mac systems are quite a few, but the most trending channels that hackers use are:

Phishing emails with links or file attachments containing malicious code
Infected applications or code from a compromised website
Drive-by downloads
Remote Desktop Protocol

How to remove adware from Mac

To remove adware on Macs, you can use an adware cleaner app or follow the steps for manual removal. If you choose the second method, you need to change your browser preferences and dig into your system files to find and remove the culprit.

Let’s start with automatic adware removal using an adware removal tool.

What is an adware cleaner app?

The name speaks for itself — it is a software application that removes unwanted advertisements and other kinds of malware secretly invading your Mac. Now, how does it work? Being designed to spot and extract viruses and malware from your computer, Mac adware cleaners do not delete important files, keeping your data safe and sound. To understand the mechanics of it, let’s take CleanMyMac X as an example.

If you want to get rid of adware on Mac manually, follow the steps below as an adware removal guide for your browser. You’ll have to remove unrecognized extensions and check your browser settings.

Tip

The easiest way to remove adware from a browser is to reinstall it. Firefox and Chrome can be easily uninstalled; however, Safari comes preinstalled, and deleting it is not as easy. For more details, check out this article on Safari removal. If you don’t want to delete your browsers, follow the tips below.

How to remove adware from Google Chrome on Mac

First, you’ll need to remove extensions. Extensions are an important part of the browsing experience, but you shouldn’t have anything that you don’t recognize. For example, if the name of a pop-up isn’t familiar or you don’t know what it does, disable it.

Here’s how to delete extensions in Chrome:

Open Chrome and go to chrome://extensions
Find any unfamiliar extensions in the list and click Remove.

Now, check browser settings. Make sure adware hasn’t changed your browser homepage or search engine settings. You’ll need to check the On startup and Search engine sections of the Chrome browser settings.

How to remove adware from Safari on Mac

The process is identical to what we followed for Chrome. First, remove unknown extensions:

In Safari, go to Settings > Extensions.
Select an unfamiliar extension from the list and click Uninstall.

Next, check browser settings. This can be done in the General and Search tabs of the Safari browser settings.

How to remove adware from Firefox on Mac

Finally, follow the same steps for Firefox. To disable extensions:

Open Firefox and navigate to Menu > Add-ons and themes.
Go to Extensions, select the ones you want to delete, and click the ellipsis icon > Remove.

To check browser settings, go to the Home and Search settings sections in Firefox.

From the Launchpad, open Activity Monitor.

Go back to your applications and drag the app to Trash.
Restart your Mac and empty the Trash.

How to protect your Mac from adware

Annoying as it is, adware is easy to avoid. Here are just a few tips that can help prevent your Mac from being infected with adware and any other malware:

Use ClearVPN’s handy shortcut to block all ads.
Google the original developer and download the app from that source.
Avoid installing apps in a bundle (an offer that’s included with the main app).
Read some independent software reviews before installing any software.
Get a Mac antivirus that works in real time. You can download a Mac cleaner app mentioned in this article — CleanMyMac X. It scans your Mac in real time and checks anything you try to install.
Conduct regular Mac virus scans with your cleaner app.
Be extremely suspicious of email attachments and visiting unsecured websites.
Don’t download anything from banners; google it yourself.
Don’t click any links unless you are sure where they lead.
Be wary of free trials and any similar offers you see in search results unless you are sure an app comes from a trusted developer.
Always monitor app permissions in the Privacy section of System Settings > Privacy & Security.

Adware seeks to steal your money and your personal details and does so by damaging system performance. If you’re worried that your Mac could be infected, err on the side of caution and follow the instructions in this post to lock down your browser and delete files.
