Malware for Mac

Has anyone used a free malware program for a Mac that you would recommend?

I guess the answer to your question would be no. Are you having an issue with malware on your Mac? I’ve been using a Mac for 25 years or so and never had an issue. Or at least an issue that caused any serious problems… I’ll keep my fingers crossed nevertheless.

What started coming across my Mac two weeks ago are fake error messages that pretend they are from Apple, e.g., we have detected a trojan virus, your gmail is corrupted, etc…I must have visited a site that is host to adware. Trying to determine the best way to stop the fake messages. Any thoughts?
