Remove "Any Search Manager" from Mac

Hello,

I updated my Flash Player from a website three days ago and have what I believe is malware on my Mac now. When I open Safari, Chrome, or Firefox, the search that comes up is now anysearchmanager.com. For a couple of seconds while it is loading, I can see something else which is akamaihd.net. How can I remove this? I have downloaded Kaspersky security, Malwarebytes, and Etrecheck but nothing is working. Thank you for any help!
