Windows Defender error 0x80016ba

[jeel]

A window with the message that Windows Defender has stopped working comes up.
I click to close it and it goes away. Sometimes it comes right back but I
keep closing it and it goes away. If I try to access Windows Defender it
gives an error message 0x80016ba. I called the tech support for my computer
let them look at my computer.
The tech said that Windows Defender file is corrupted. First question..how
did that happen? I am running Secure IT so he said I don't need Windows
Defender. Is that a correct assumption. He said if I try to reinstall
Defender I will loose all my info and settings. Is that correct? If I don't
want to ignore the Defender messages is there a way to remove it? Thank you
