I'd Say Malwarebytes for Mac:

Malwarebytes searches for malware (short for (malicious software) and spyware. Those make your Mac act in a mislead manor. So scan with it, and remove what is found from the quarantine. It is created by longtime users of these forums making it the only reliable Security Software for a Mac. If synced with iPad connected, it may have got installed on your Mac.

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller

Your brain, and what has already been shared.

"Security" is a broad subject as well as a personal responsibility that cannot be delegated to an app.

Well put & succinct! 👍
