Is there free malware for macs?

Why would you want malware free or not?

Malwarebytes finds and gets rid of malware - it is not malware.

Check their site for your options.

Yes, Malwarebytes is still free. You don't have to purchase the full version (which runs in the background).

There’s no malware that isn’t already blocked by the built-in tools.

If you were foolish enough to install adware, the free Etrecheck should be able to remove it.
