Apple Mac message re legacy system Extension

I am getting a message to say that my Trend Antivirus for Mac is out of date and will not be compatible with next up date by Apple. I am running the latest version of Mac opersting system and keep my Trend Antivirus up to date. I purchased my Trend AntiVirus in 2019 for multiple devices and multiple years. I also have Trend installed on iPads, Android phones and a Windows laptop.

I am attaching some screen shots of messges and system information.

Do I have to uninstall my current Trend Antivirus and then reinstall the new version, or can I updtae my existing Trend without uninstalling the current package?

No need to uninstall your current Trend Micro Security program. You may just follow the instruction on this link on how to update your Antivirus Security for Mac
