Monterey update 12.5.1 issues

No Problems here using Safari 15.6.1 on Monterey 12.5.1.

Able to log into all 4 Banks I use, 1 Financial Institution and both Credit Card Companies and 2 Government Website including Income Tax Site of the Government

What exactly occurs with your site ? Some Error message of Access Denied Message ?

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. 

Additionally, and specific to Big Sur macOS 11 and Monterey macOS 12, the Operating System resides in a Sealed and Read Only Volume that can not be opened by the User and protects against from “ Bad Actor “ Software.

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.

AntiVirus Developers purposefully Market their product to create a “ Fear Factor “. In so doing, creating a False Need for their Product.

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

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprising the Operating System

Certain Applications maybe available on the Apple Apps Store - this only means the Developer is prepared to pay Apple a portion on each sale. What the Application may do to the computer is up to the User to check this out before purchase

Any of the below should be removed as per Developers Instructions

This will include CleanMyMac , This will include BitDefender , 

This will included Norton Antivirus , Sophos Av Software

Intego AntiVirus, McAfee, MacKeeper, Avast AntiVirus

Ad Guard, Webroot , ESET , Kaspersky Antivirus. Anti virus

AVG AntiVirus <<<<

Trustee <<<<

Please read some of the posting specific to both Applications in question and then arrive at your own conclusions.

The suggestions have been put forth on a volunteer basis, in good faith and in the best interests of the computer.

If the suggestion is " out side your comfort zone " , nothing wrong with that and takes a big person to admit - then Yes, a trip to to your nearest Apple Store maybe your better choice .

In my case, the link provided will as Safari to use Location Service to better direct you to closest Apple Store based in your actual location

Apple Store - Find a Store - Apple (CA)

I’ve used both Trusteer and AVG on the same MacBook Pro for over 20 years without issue, until the Monterey 12.5.1 update.

That's not possible. Monterey will not run on a MacBook Pro earlier than 2015. Plus, the very first MacBook Pro only came out 16 years ago.

You are welcome and thank you too 🇨🇦

Do come back to the Apple Support Communities ( ASC )  in the future, if / or when additional questions may arise
