Third party AntiVirus is not recommended— it typically does nothing but add issues to the macOS and competes directly with Apples own built in security:

macOS - Security - Apple https://www.apple.com/macos/security/

Apple Platform Security - Apple https://support.apple.com/guide/security/welcome/web

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX  Foundation and Permission Limitation. 

The Only thing this Antivirus software is protecting is the Bank Account of the Developers and for zero return to the User aside from the problems this software creates.

Any Third Party Applications that will interfere with the normal operation of the OS, alter, modify, remove or delete or attempt to do so is an invitation for disaster and may require a Reinstallation of the OS.

This includes AntiVirus, Disk Cleaners, Disk Optimizes, UnInstaller etc.

This will include CleanMyMac 

This will include BitDefender 

This will included Norton Antivirus

Sophos Av Software

Intego AntiVirus

McAfee

MacKeeper

Avast AntiViru 

Ad Guard

The The Built in Security  is all that is required.

None is needed and is recommended.

Just update your macOS to the latest version.

NONE
