Password Manager pop-up

Each time I start typing a password on a web site, Password Manager pops up saying " Would like Password Manager to remember the password for User on com. Options Never for this site, then buttons Remember  No, thanks"  How do I disable or prevent this pop-up from appearing? I would appreciate anyone's advice. This pop-up really distracts me while typing the password. I have never activated Norton Password Manager, neither have I signed in to Vault. Even though I check the box "Never for this site", this pop-up shows up the next time I log in to the same web site. I have Internet Explorer 11 installed on my Windows 10 computer.
