mac book air security

Hello, msbogey.

There is no good reason to buy and install Trend Micro Internet Security on your new MacBook Air.

Anti-virus, clean up, and optimizing apps are unnecessary on the Mac, and very often cause more problems than they claim to prevent. Few veteran Mac users here will recommend the use of apps of this type.

MacOS has its own built-in securities and is pretty secure as long as you keep it updated.

Some light reading on the subject:

Effective Defenses Against Malware (John Galt)- Apple Community

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 The Built in Security  is all that is required to protect the computer.

Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac. 

It is free or paid for added features.

Run the Application and it should remove the malware / adware. Once done, restart computer and test.

Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation. 

You're welcome.

Since the release of Catalina, and continuing with Big Sur and Monterey, macOS has gained some additional security with the read-only APFS volumes that it is now required to be installed on. Apple continues to take steps to secure the OS and prevent tampering by unauthorized software. I think that's generally a good thing.
