I see that you would like to bypass scanning for browser passwords in the machine. I'm afraid we won't be able to setup or configure that setting because, for now, we do not have a way to do that. For the meantime, kindly ignore the message to make improvements regarding the unprotected browser passwords if you do not wish to install the Password Manager.
No worries, the Trend Micro program does not save or somewhat read the passwords that are saved in your internet browsers. It is a way for us to promote the Trend Micro Password Manager program that is actually bundled with the Maximum Security license.
Kindly do not hesitate to post here in case you need further help or if you have any other inquiries.
