How to disable Norton Browser Extension Pop Up

After getting anti-virus for some work computers I was excited to set everything up. Sadly many of the workers continue to get pop ups in their browsers telling them to install the Norton Browser Extensions.

We do not want the extensions. We never wanted the extensions. All we wanted was the anti-virus.

Is there a way to block this pop up from disappearing on our browsers? And no, do not tell me to disable special offers in the settings. That has been done already. We've also tried manually blocking pop ups from search.norton.com in our browsers. Still doesn't work.

I'm extremely frustrated that the supposed anti-virus that I paid for actually just ends up being adware for my staff. We clearly don't want to install these extensions. If this isn't fixed we will not be renewing our subscription with this software.
