I thought Norton automatically screens incoming email. Well, a trojan, sent by email was implemented on my 2019 iMac recently. I found out not by a Norton alert but by an Apple alert notifying me of an unauthorized device on my computer. Removing the ghost device was easy, but finding the trojan not so. Both Quick Scan and Smart Scan could not find it. It took a complete scan to find which was then removed by Norton.
It was disappointing to say the least. Getting a trojan via email is one of the most used means of attack. What happened? Does Norton not screen email?
This is unnerving.
Norton only scans files when they are opened or run; it does not scan email content itself. Because of this, trojan attack was not discovered until it was scan by the system, but the threat activated later, and the file was delivered safely Via email.
It is good to do routine full scans, and turn on real time protection to avoid unknown attachments.

FWIW!! Norton doesn’t scan IMAP email clients on Mac nor Windows. It DOES scan POP and SMTP. Reviewing messages from senders not recognized and messages with attachments should be reviewed by the user primarily. The email protection Norton provides in the current products is basically worthless as is now is, many of us hope that changes in the near term vice never. The focus seems to be on products that aren’t really needed and related to AI and data gathering. Its the new future for software companies.
