Window opens to "Kav_agent quit unexpectedly" message after login on brand new macair running Ventura.

This is a brand new mac. I used migration assistant to restore my time machine backup from my old mac running Catalina. I have never used Kaspersky on my previous mac, and this mac does not come with it installed. I don't know why I get this messsage, and I can't seem to find any answers to how to stop it. Any help would be greatly appreciated.

MacBook Air, macOS 13.2

Judging from the link below, this "Kav_Agent " is connected to Kaspersky AV on your Mac


Kav_Agent - Apple Community


Though you say it was Never Installed on previous computer when it was Migrated to the new machine it appears it may have been there and possible Removed ?


If Elements of that software were left behind on the Older Machine - it may have Migrated to the New Computer.


This can happen by accident.


Download the Application Etrecheck directly from the Developer.

It makes a coherent and readable inventory of both the Hardware and Software used on the computer 


The application is free or paid from added features.

Thanks for the info. I really appreciate it! Not sure how I have kapersky on my mac. Maybe I tried a free version many macs ago and this relic was left behind and followed me to newer macs. I am curious, though, as to why this message window does not appear on the mac from which I migrated? (running Catalina) Or the macbook before that?


In any case, Could you please tell me how to remove it.

Thanks in advance
