First, uninstall whatever antivirus product you bought. Those things are scams that range from useless to malicious. Follow its uninstallation instructions.

Then, please read Removing "Search Marquis" / "Search Baron" / etc on your own - Apple Community. Capture and post the three separate screenshots it describes in a reply to this Discussion.

If for whatever reason you are unable to load that web page, you will need to restart your Mac in "Safe Mode". Those instructions are here: How to use safe mode on your Mac - Apple Support, but if you can't load that web page either the relevant excerpt follows.

Start up your Mac in safe mode

Starting up your Mac in safe mode can help you identify whether issues you're experiencing are caused by software that loads as your Mac starts up.

Before you begin

To start up your Mac in safe mode, you need to know what type of Mac you have.

1. On your Mac, choose Apple menu  > About This Mac.
2. Look at the information in the Overview pane to determine what type of Mac you have:

• If you see an item labeled Chip, followed by the name of the chip, you have a Mac with Apple silicon.
• If you see an item labeled Processor, followed by the name of an Intel processor, you have an Intel-based Mac.

Use the corresponding set of instructions below to start up your Mac in safe mode.

Start up your Mac with Apple silicon in safe mode

1. On your Mac, choose Apple menu > Shut Down.
2. Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.
3. Press and hold the power button on your Mac until "Loading startup options" appears.
4. Select a volume.
5. Press and hold the Shift key, then click Continue in Safe Mode.
6. The computer restarts automatically. When the login window appears, you should see "Safe Boot" in the menu bar.

Start up your Intel-based Mac in safe mode

1. Turn on or restart your Mac, then immediately press and hold the Shift key until you see the login window.
2. Log in to your Mac.
3. You might be asked to log in again.
4. On either the first or second login window, you should see "Safe Boot" in the menu bar.

Verify your Mac started up in safe mode

If you're unsure whether your Mac started up in safe mode, you can use the System Information app to check the mode.

1. On your Mac, choose Apple menu  > About This Mac.
2. Click System Report.
3. In the System Information app, select Software in the sidebar.
4. In the System Software Overview, look at the value listed next to the item labeled Boot Mode.

• Safe: The Mac is using safe mode.
• Normal: The Mac is not using safe mode.

For more information about using safe mode, see the Apple Support article How to use safe mode on your Mac.

Once your Mac is in "Safe Mode" you will be able to click links including the User Tip above. You can capture those screenshots and post them to this site while in that mode also.

Culpw0, follow the instructions below.

First, ensure you have a reliable backup of your Mac, in case something should go wrong with continued troubleshooting. To learn how to do that, please read Back up your Mac with Time Machine.

• A backup is a fundamental prerequisite regardless of whatever method you may choose uninstall adware, and would apply even if your Mac were running perfectly well. Do not overlook this fundamental requirement. It's important.

Next: This step will prevent the scam products from loading so that they can be removed while they are inactive. Restart in "Safe Mode", and log in: Use safe mode to isolate issues with your Mac. Starting in Safe Mode takes longer than usual so let it finish. The rogue processes affecting that Mac are inoperative in "Safe Mode".

The following files and / or folders need to be deleted while using your Mac in "Safe Mode":

Nothing needs to be deleted from the folders in the first two screenshots.

Third screenshot:

Delete all those files except the two with google in their names.

Drag those selections of files to the Trash. You may be asked to authenticate. Confirm they are no longer present in that folder. Leave all the others alone for now.

Next: open Safari and select the Safari menu > Preferences... > Extensions. If you see any Safari Extensions that you do not recognize or understand, simply click the Uninstall button and they will be gone. No Safari Extensions are required for normal operation. Then, select the General pane and review your Homepage selection. Repeat those equivalent actions for any other browser you may use (Brave, Firefox, or Opera for example).

There may also be adware-associated app icons in your Mac's Applications folder. Open it and examine its contents. Any unwanted or mysterious app icons should be obvious to you, but again please don't remove anything if you are uncertain—ask first. Identify any suspicious apps by name, or post another screenshot.

Next: In an abundance of caution, examine System Preferences > Extensions. Determine if there are any System Extensions that may have been installed without your knowledge. Ask if you're uncertain.

Remaining in System Preferences, check for the presence of any Profiles. Profiles are installed by organizations with a need to manage Macs deployed in institutional corporate or educational environments (for example), but have also been exploited by adware creators and similar malcontents. If any Profiles are installed on your Mac an icon like this will appear in System Preferences:

If you see that icon in System Preferences, select it. To remove a Profile, select it, then click the [—] (minus) button and authenticate.

Remaining in System Preferences, open Users & Groups. Select your User Account's Login Items. You may or may not find those Applications in its list. If you do, select them then click the [—] (minus) button to remove them from Login Items.

You can then restart your Mac and log in as usual. Evaluate its operation and ensure everything is working as you expect it should.

Next: if you want to eradicate all remaining adware remnants post a screenshot of the following folder, in the same manner as you did earlier:

~/Library/Application Support

It is normal for that folder to contain many items, but anything associated with the above adware may contain identical names. If you find a folder or folders bearing those names, drag those folders to the Trash. Without the files you already removed or the reintroduction of similar malware, they can do nothing but occupy space. These can be removed if you wish, but again don't remove anything if you are uncertain.

Finally: If any of the above actions result in abnormal operation or if something else stops working, the easiest way to recover would be to restore the Time Machine backup you created as a prerequisite, so the importance of that fundamental step cannot be overemphasized.
