Searchbaron and searchmarquis have highjacked my mac computer. How do I get rid of them?

You can use the etrecheck for removing adware/malware—

trusted utility https://etrecheck.com

this can work better than the alternative https://www.malwarebytes.com/mac/

I tried both of these programs. Neither detected the searchmarquis malware. Any other suggestions?
