Remove AnalyzerFormat Adware [Virus Removal Guide]

AnalyzerFormat is a potentially unwanted program that injects advertisements into websites you visit and redirects your browser search queries.

Advertisements

What is AnalyzerFormat?

AnalyzerFormat is a malicious program that hijacks your browser homepage and search engine and displays unwanted advertisements not originating from the sites you are browsing. To do this, AnalyzerFormat uses a browser extension or program.

Advertisements

When installed on a computer, the AnalyzerFormat browser hijacker will redirect your browser search queries through AnalyzerFormat Search, which will redirect to search result pages from search.yahoo.com. This is most likely done to generate advertising revenue by using Yahoo Search for its search results.
AnalyzerFormat will also open new tabs in the browser that display advertisements trying to sell software, push fake software updates, and tech support scams.

When the AnalyzerFormat browser hijacker is installed on a computer, common symptoms include:

Your web browser’s default search engine is AnalyzerFormat Search
Your browser’s search queries are redirected through AnalyzerFormat Search
The “AnalyzerFormat” browser extension or program is installed on your Mac

How was AnalyzerFormat installed on my computer?

AnalyzerFormat is installed by the users, whether that is knowingly or not. Often, this type of program is offered through advertisements or bundled with other software, leaving the user puzzled about where this software came from.
Unfortunately, some free downloads do not adequately disclose that other software will also be installed and you may find that you have installed AnalyzerFormat without your knowledge.

Removal instructions for AnalyzerFormat browser hijacker

This malware removal guide may appear overwhelming due to the number of steps and numerous programs that are being used. We have only written it this way to provide clear, detailed, and easy-to-understand instructions that anyone can use to remove malware for free.
Please perform all the steps in the correct order. If you have any questions or doubts at any point, stop and ask for our assistance.

To remove AnalyzerFormat from your Mac, follow these steps:

STEP 1: Remove malicious profiles
STEP 2: Delete malicious apps
STEP 3: Reset browsers back to default settings
STEP 4: Run a scan with Malwarebytes for Mac to remove malware

STEP 1: Remove malicious profiles

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.

Advertisements

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 Settings”

From the Apple menu () in the top-left corner of the screen, select System Settings. (On macOS Monterey and earlier, this is called System Preferences.)
Look for “Profiles”

Where you find configuration profiles depends on your version of macOS:

macOS Sequoia (15) and later: click General in the sidebar, then click Device Management. You may need to scroll down.

macOS Ventura (13) and Sonoma (14): click Privacy & Security in the sidebar, then click Profiles near the bottom.

macOS Monterey (12) and earlier: in System Preferences, click Profiles.

You can also type “Profiles” in the search box.

No profiles listed, or no Profiles section at all? That means no configuration profiles are installed on your Mac, which is completely normal. Skip ahead to the next step of this guide.
Remove the malicious profiles

Malware uses configuration profiles to lock your browser settings — forcing a fake search engine or homepage on you and preventing you from changing it back. If you see a profile you don’t recognize (and your Mac isn’t managed by your workplace or school), select it, press the − (minus) button, and click Remove to confirm.

STEP 2: Delete malicious apps

In this second step, we will try to identify and remove any malicious apps and files that might be installed on your computer. Sometimes redirects or adware programs can have usable Uninstall entries that can be used to remove these programs.

Quit the malicious programs

Check the Apple menu bar in the top-right corner of your screen. If you see an icon you don’t recognize, click it and select Quit. This stops the malware from running so it can’t interfere while we remove it.
Open “Finder”

Click the Finder icon in your dock.
Click on “Applications”

In the Finder sidebar, click “Applications“.
Find and remove the malicious app

Scroll through the list of installed apps and look for anything suspicious — an app you don’t remember installing, or one with a strange or generic name. When you find it, right-click it and select “Move to Trash“.

Some known malicious programs to look for: SearchMine, TakeFresh, TopResults, FeedBack, ApplicationEvents, GeneralOpen, PowerLog, MessengerNow, ImagePrime, GeneralNetSearch, Reading Cursors, GlobalTechSearch, PDFOnline-express, See Scenic Elf, MatchKnowledge, Easy Speedtest, and WebDiscover. The names change constantly, though — so treat any app you can’t account for as suspect.
Empty the Trash

Before you empty the Trash, check that it doesn’t hold anything else you want to keep, because emptying it permanently deletes everything in it. Then right-click the Trash icon in your dock and select “Empty Trash“.
Check login items and background apps

Malware often sets itself to start automatically. Open the Apple menu > System Settings, click General, then click Login Items & Extensions (called Login Items in macOS Ventura and Sonoma). Look for apps you don’t recognize in the list of items that open at login and in the list of apps allowed to run in the background. Select an unwanted item and click the Remove (−) button, or turn off its switch.

This check doesn’t delete any files. Note the names you find, because they help you spot related files in the next step.
Find and remove the malicious files

Malware on Mac uses launch agents and launch daemons — small files that automatically restart the malware every time you boot your Mac. We’ll check the four folders where they hide:
1. Click the desktop to make sure you’re in Finder, then open the “Go” menu and click “Go to Folder“.
2. Copy and paste each of the paths below into the window, one at a time, and click Go after each:
  - /Library/LaunchAgents
  - ~/Library/LaunchAgents
  - /Library/Application Support
  - /Library/LaunchDaemons
3. In each folder, look for suspicious .plist files — typically named after the malware or with odd, random-looking names. Examples seen in past infections include “installmac.AppRemoval.plist”, “myppes.download.plist”, “mykotlerino.ltvbit.plist”, and “com.myppes.net-preferences.plist”. A name alone is not proof. For example, “com.adobe.fpsaud.plist” belongs to Adobe’s own Flash Player updater. When you find a malicious file, move it to the Trash — then empty the Trash again when you’re done.
  Be careful: these folders also contain files belonging to legitimate apps — especially /Library/Application Support, where programs like Adobe, Google, and Microsoft store their data. Only delete files you’re confident are malicious. If you’re unsure about a file, search its exact name online first, or leave it in place and continue with the Malwarebytes scan later in this guide.

STEP 3: Reset browsers back to default settings

In this third step, we will remove spam push notifications and malicious extensions, and change to default any settings that might have been changed by malware.
For each browser that you have installed on your computer, please click on the tab below and follow the displayed steps to reset that browser.

Remove malicious extensions and settings from Safari

To remove malware from Safari we will check if there are any malicious extensions installed on your browser and what settings have been changed by this malicious program.

Go to Safari’s “Settings”.

On the menu bar, click the “Safari” menu and select “Settings”. In older versions of Safari, this menu item is called “Preferences”, as in the image below.
Check Homepage.

This will open a new window with your Safari settings, opened to the “General” tab. Some browser hijackers may change your default homepage, so in the Homepage field make sure it’s a web page you want to use as your start-up page.
Click “Extensions”

Next, click on the “Extensions” tab.
Find and uninstall malicious extensions.

The “Extensions” screen will be displayed with a list of all the extensions installed on Safari. Look out for any suspicious browser extension that could be behind all the drama – anything you don’t remember downloading or that doesn’t sound like a genuine extension. By default, there are no extensions installed on Safari so it’s safe to remove an extension
Remove spam notifications ads

In Safari’s settings, click Websites, then click Notifications. Find the website that sends the spam notifications, then choose Deny from the menu next to it.

To stop other websites from asking, you can also deselect “Allow websites to ask for permission to send notifications“. This only blocks new requests. It doesn’t turn off websites you already allowed, so deny those websites as well.

You can also turn off a website’s notifications in System Settings > Notifications. Under Application Notifications, click the website and turn off Allow Notifications.
Remove the data stored by the unwanted website.

In the Safari menu, choose “Settings…”, select “Privacy” at the top of the new window that appears, and then click the “Manage Website Data” button.

In the next dialog box, search for or select the website that showed the spam or redirects, then click “Remove“. Click Done when you’re finished.

Avoid “Remove All” unless you really need it. It deletes the data of every website and can sign you out of all of them.
Empty Safari Caches.

From your Safari menu bar, click Safari and select Settings, then select the Advanced tab. Enable the checkbox “Show features for web developers“. In older versions of Safari, this checkbox is called “Show Develop menu in menu bar”, as in the image below.

From the menu bar select Develop, then click on Empty Caches as seen in the image below.

Remove malware from Chrome for Mac

To remove malware from Chrome for Mac we will reset the browser settings to their defaults. This restores the default search engine, homepage, new tab page, and pinned tabs. It also resets site permissions, clears cookies and site data, and turns off your extensions and themes. Your bookmarks and saved passwords are not deleted. If you’re signed in to Chrome, the reset applies on all devices where you’re signed in.

Click on the three dots at the top right and go to Settings.
Click on Chrome’s main menu button, represented by three dots at the top right corner. Now click on the menu option labeled Settings as shown by the arrow in the picture below, which will open the basic settings screen.
In the left sidebar, click on the “Reset settings” option.
In the left sidebar, click on “Reset settings“.
Click “Restore settings to their original defaults”.
Now click on “Restore settings to their original defaults” as shown in the image below.
Click “Reset Settings” button.
A confirmation dialog should now be displayed, detailing the components that will be restored to their default state should you continue with the reset process. To complete the restoration process, click on the “Reset Settings” button.
(Optional) Stop sync from bringing the problem back.
If a malicious extension or setting comes back after the reset, Chrome sync may be restoring it from your Google Account. Open Chrome Settings > You and Google. If you see Sync and Google services > Manage what you sync, choose Customize sync and turn off Settings and Extensions. In newer versions of Chrome, click your account name, then Choose what to save in your Google Account, and turn off the same two items. Then remove the unwanted extension again.
Don’t use the “Delete data” or “Clear data” option on your Google Account’s Chrome data page to fix this. It deletes the Chrome data saved in your Google Account, such as synced bookmarks, passwords, and history, and you don’t need it to remove an extension.

Remove malware from Firefox for Mac

To remove malware from Firefox for Mac we will reset the browser settings to its default. The reset feature fixes many issues by restoring Firefox to its factory default state while saving your essential information like bookmarks, passwords, web form auto-fill information, browsing history, and open tabs.

Go to the “Help” menu.

Click on Firefox’s main menu button, represented by three horizontal lines. When the drop-down menu appears, select the option labeled “Help“.
Click “More troubleshooting information”.

Next click on the “More troubleshooting information” option as indicated by the arrow in the image below. This opens the Troubleshooting Information page. You can also open it by typing about:support in the address bar.
Click on “Refresh Firefox”

Click the “Refresh Firefox” button in the upper-right corner of the “Troubleshooting Information” page.
Confirm.

To continue, click on the “Refresh Firefox” button in the new confirmation window that opens.
Click on “Finish”.

Firefox will close itself and will revert to its default settings. When it’s done, a window will list the information that was imported. Click on the “Finish“.

Your old Firefox profile will be placed on your desktop in a folder named “Old Firefox Data“. If the reset didn’t fix your problem you can restore some of the information not saved by copying files to the new profile that was created. If you don’t need this folder any longer, you should delete it as it contains sensitive information.

STEP 4: Run a scan with Malwarebytes for Mac to remove malware

In this final step, we will scan the computer with Malwarebytes for Mac to find and remove any malicious programs that might be installed on your Mac.

Malwarebytes for Mac is a free on-demand scanner that removes the malware other security software tends to miss — adware, browser hijackers, and unwanted programs included. Cleaning an infected Mac with Malwarebytes has always been completely free, and it’s our go-to recommendation. Follow the steps below to scan your Mac and remove what Malwarebytes finds.

Download Malwarebytes for Mac

The Malwarebytes for Mac Installer will guide you through a few quick screens. Click “Continue” and keep following the prompts until the installation completes.

When the installation is complete, Malwarebytes opens to the Welcome to Malwarebytes screen. Click “Get started“.

Malwarebytes needs Full Disk Access to check your whole Mac. When it asks, open System Settings > Privacy & Security > Full Disk Access, turn on Malwarebytes (it may be listed as Malwarebytes Protection), and confirm with your password or Touch ID. Then return to Malwarebytes. On macOS Monterey and earlier, this setting is in System Preferences > Security & Privacy > Privacy.
Select “Personal Computer” or “Work Computer”

Malwarebytes will ask what type of computer you’re installing it on. Click either Personal Computer or Work Computer, whichever applies.
Start the Scan

Click the “Scan” button. Malwarebytes will automatically update its detection database and begin checking your Mac for malware.
Wait for the Scan to Finish

Malwarebytes will scan your Mac for adware, browser hijackers, and other malicious programs. This can take a few minutes, so feel free to do something else — just check back occasionally to see the progress.
Quarantine the Detected Threats

When the scan is done, you’ll see a list of everything Malwarebytes found. Click the “Quarantine” button to remove all the threats at once.
Restart Your Mac

Malwarebytes will now remove all the malicious files it found. Some threats can only be fully removed after a reboot — if Malwarebytes asks you to restart, allow it. Once you’re logged back in, check whether the problems you noticed have stopped. If they come back, save the scan report and ask for help in our forum.

Your computer should now be free of the AnalyzerFormat browser hijacker and other malware.
