If you have adware/malware installed. Download this program which was written by Thomas Reed, a long time poster. The program will search for malware/adware The program will do the work for you which makes it easy. It may be necessary to run more than one scan. After scanning a couple of times, restart the computer, and test.

If you start your Mac in "Safe Mode" (read below) you should be able to open Safari Preferences.

Then, refer to Removing "Search Marquis" / "Search Baron" / etc on your own - Apple Community and post those three screenshots in a reply to this Discussion.
You are welcome.
Have you tried restarting the computer? Are you running any anti - virus programs? Using a VPN?
Try setting up another admin user account to see if the same problem continues. The intent is to see if it is specific to one account or a system wide problem. This account can be deleted later.
Isolating an issue by using another user account
If the problem is still there, try booting into the Safe Mode using your normal account. Disconnect all peripherals except those needed for the test. Shut down the computer and then power it back up after waiting 10 seconds. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the gray Apple icon and a progress bar appear. The boot up is significantly slower than normal. This will reset some caches, forces a directory check, and disables all startup and login items, among other things. When you reboot normally, the initial reboot may be slower than normal. If the system operates normally, there may be 3rd party applications which are causing a problem. Try deleting/disabling the third party applications after a restart by using the application un-installer or by using the developer’s uninstall instructions. For each disable/delete, you will need to restart if you don't do them all at once.
