Extension Settings is a Chrome browser extension that injects advertisements into websites you visit and redirects your browser search queries.
What is the Extension Settings extension?
Extension Settings is a malicious Chrome browser extension that displays advertisements in the browser. When installed, this extension will open new tabs in the browser that display advertisements trying to sell software, push fake software updates, and tech support scams.

STEP 1: Remove malicious Profiles from your Mac
Profiles are used by IT admins in businesses to control the behavior of their Macs. These profiles can configure a Mac to do many different things, some of which are not otherwise possible.
When it comes to home users, adware and browser hijackers are using the configuration profile to prevent users from removing malicious programs from the computer. This also prevents the user from changing that behavior in the browser’s settings.
In this first step, we will check your computer to see if any configuration profiles are installed. To do this, follow the below steps:
-
Open “System Preferences”
From the Apple menu, select System Preferences.
-
Search for “Profiles”
When the System Preferences window opens, search for the Profiles icon.
If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal and you can continue with the next steps. -
Remove the malicious profiles
If there’s a Profile icon, click on it and select any suspicious profile that you want to remove, and then press the – (minus) button. Click Remove to remove the profile.
STEP 2: Remove Extension Settings from Mac
In this next step, we will uninstall Extension Settings and remove its files from your computer. Sometimes adware and browser hijackers can have a usable Uninstall entry that can be used to remove them.

Find and remove Extension Settings.

In this third step, we will download, install and run a scan with Malwarebytes for Mac to remove Extension Settings and other malware from your computer.

Workaround for greyed out Safari’s homepage
In some cases, after being changed by browser hijackers or malware, Safari’s home page can become stuck (greyed out). You will be able to edit the Homepage field in Safari’s preferences, but the change will not stick. This appears to be a bug, and there is an odd workaround. Try this:- In Safari, choose Preferences from the Safari menu.
- In the window that opens, click the General icon (if necessary)

If the above steps didn’t help you remove the Extension Settings browser hijacker from Chrome, you can follow the below steps:
-
Remove the unwanted policies created by malware from Chrome
In many cases, changes to Chrome may not be fixed with a simple browser reset. In such a case, a malicious program may have created unwanted policies on your browser. You can check if any unwanted policies are loaded into the browser by typing chrome://policy into the URL bar.
To reset these policies, follow these steps:- Open a new Terminal window. To do this, go to Finder > Go > Utilities > Terminal
- Enter the following commands, pressing enter after each line:
- defaults write com.google.Chrome HomepageIsNewTabPage -bool false
- defaults write com.google.Chrome NewTabPageLocation -string “https://www.google.com/”
- defaults write com.google.Chrome HomepageLocation -string “https://www.google.com/”
- defaults delete com.google.Chrome DefaultSearchProviderSearchURL
- defaults delete com.google.Chrome DefaultSearchProviderNewTabURL
- defaults delete com.google.Chrome DefaultSearchProviderName
- defaults delete com.google.Chrome ExtensionInstallSources
- After running these commands, quit Chrome if you haven’t already done so, then launch it again and check chrome://policy to see if the same keys are still present (you may need to click the “Reload policies” button for changes to show up). If they’re gone, you should be able to change your search engine and home page back to your preferred defaults in Chrome’s settings.
-
Remove the “Managed by your organization” policy from Chrome
Some malicious programs are known to install managed preferences to set the home page and search engine settings in Chrome. To check for these, do the following:- Quit Chrome
- Click the desktop to make sure you’re in the Finder, choose “Go” then click on “Go to Folder“.
- Type or copy/paste the following path into the window that opens, then click Go: /Library/Managed Preferences/
- Paste the below path into the window that opens, then click Go:
Look for the following files, where [username] is your username:- com.google.Chrome.plist
- [username]/com.google.Chrome.plist
- [username]/complete.plist
These may be legitimate, so open these files with TextEdit and see if they have links to the troublesome site in them. If they do, delete them and restart Chrome.
-
Uninstall Google Chrome from your computer
If the above options didn’t help you remove the malicious redirects, it is easier to completely remove Chrome and all data, then reinstall the browser. To do this, click the Finder icon, from the menu bar. Choose Go, and click Go to Folder, then paste one of the below paths into the window that opens.
You will need to delete all of the below items, but before doing this be aware that this will delete all data for all Google apps you have installed, such as your bookmarks, so you will need to export them before doing this.- /Applications/Chrome.app
- /Library/Application Support/Google/
- /Library/Google/
- ~/Library/Application Support/Google/
- ~/Library/Google/
- ~/Library/Preferences/com.google.Chrome.plist
Note: The “~” indicates that it’s the current user’s Library which is often invisible in recent versions of macOS. To get to it you must hold down the Option (sometimes labeled Alt) key and select Library from the Finder’s Go menu.
After deleting all of the above files, restart your device. You can now download and re-install Google Chrome on your device. You will need to import any exported bookmarks or other data and may need to reinstall any other Google apps that you use.
