How to get rid of adware on your Mac

Adware is an unwelcome intrusion in many browsers. It attempts to trick or force you into clicking through to a website you weren't planning on visiting, to generate revenue for the company that produced it. Some versions of ad software also contain hidden viruses, posing a serious risk to your Mac and data it contains.

Fortunately, there are ways to remove this rogue software manually via your browser and your system files, and with a cleaner tool like CleanMyMac X. We’ll take you through each of these methods to help you get rid adware on your Mac for good.

The symptoms of an adware infection

Take a look at these symptoms to see if any are familiar:

  • Several pop-ups appearing when you click on links that advertise fake updates or software
  • More ads than you’re used to in search results and webpages — particularly banner ads or in-text advertisements in content
  • Your homepage redirects to another website
  • The link that you click in search results redirects to a different website
  • Mac performance seems much slower than usual
  • Unwanted toolbars appearing in your browser

If you’ve noticed any of things happening when browsing the internet on your Mac you’re almost certainly dealing with adware. In which case, you need to take action.

This is how adware actually looks like

This string of code is an example of adware program on Mac. As you can see in the third line, it "loads offers" for the user which to you look like intrusive banners and pop-ups.

How to remove adware from your browser

To remove adware from your Mac you need to change your browser preferences and dig into your system files to find and remove the culprit.

Let’s start with the browser. How to stop adware in your browser:

1. Block all pop-ups

The first thing you should do to curb the onslaught of nuisance ads is close all pop-ups. DO NOT DO THIS BY CLICKING ON ANY BUTTON IN A POP-UP. Instead, click on the X in the top left of the window.

If the pop-up refuses to close, press Command+Option+Escape to open the Force Quit window. Select your browser from the list and click Force Quit. Hold down Shift when restarting your browser to stop any previously opened windows from reappearing.

Next, in the Safari Preferences click on the Security icon and select Block pop-up windows.

If you’re a Chrome user, follow these instructions to block pop-ups:

  1. Click on the three dots in the top right corner of the browser.
  2. Select Settings, then Show Advanced Settings > Privacy > Content Settings.
  3. In Pop-ups, block the ability for any site to show pop-ups.

2. Disable unrecognized extensions

Extensions are an important part of the browsing experience but you shouldn’t have anything that you don’t recognize. If the name of a pop-up isn’t familiar or you don’t know what it does, disable it.

Disabling extensions in Safari

  1. Go to Preferences > Extensions.
  2. Select an unfamiliar extension from the list and click Uninstall.

Disabling extensions in Chrome

  1. Go to Settings > Extensions.
  2. Find any unfamiliar extensions in the list and uncheck the Enabled box.

3. Check homepage and search engine settings

Finally, make sure adware hasn’t changed your browser homepage or search-engine settings.

This can be done in the General tab of the Safari browser settings or in the On Startup and Default Browser sections of the Chrome browser settings.

How to remove adware from your system

Tackling adware in your browser will help to improve your browsing experience but it doesn’t guarantee to completely free you from the virus.

Adware often finds its way onto your system by bundling itself in with legitimate Mac software and is installed at the same time. So you’re going to need to delve into your system files to root out the adware and delete it. You can do this manually or with an application like CleanMyMac X.

Because of the way a manual deletion works (sending files to the Trash), CleanMyMac X is the preferred option. A file placed in the Trash and removed can leave behind associated files that lie deep inside system files, meaning the pesky adware still exists on your Mac. CleanMyMac X, on the other hand, scans your system for any leftover parts and removes them in full.

Remove adware from Mac with CleanMyMac X

CleanMyMac X can detect and remove thousands of threats, including adware, viruses, worms, spyware, and more. With its dedicated Malware Removal tool, you’ll stay safe.

Here’s how it’s done:

  1. Download CleanMyMac X and launch it.
  2. Click on Malware Removal from the sidebar menu.
  3. Click Scan.
  4. Click Remove.

Another useful feature of CleanMyMac X is real-time monitoring. It checks your Mac in a background mode and notifies you if any adware app attempts to infiltrate your Mac.

Remove adware from your Mac manually

If you’d prefer to remove potential adware manually before opting for an app like CleanMyMac X, it’s easy to do, albeit a little more time-consuming.

  1. From the LaunchPad open Activity Monitor.
  2. Find the suspect applications (Genio and InstallMac are common culprits) and click the Force Quit button in the top left corner of the window.
  3. Go back to your applications and drag the app to the Trash.
  4. Restart your Mac and empty the Trash.

Never engage with adware

Adware seeks to steal your money and your personal details and does so by damaging system performance.

If you suspect that adware has installed itself on your system, get CleanMyMac X to ensure you get rid of it for good.
