Hello Linkey,
Does AutoUpdate work on your system?
Try going to Windows Update and applying all offered critical updates.

AutoUpdate--the native automatic update mode of Windows Defender uses the
BITS service. This service is specifically designed, to minimize bandwidth
impact.

The right strategy for a dialup user is just to ignore the update
process--let the bits service do its thing--dial in when you want, hang up
when you want. Bits should use unused bandwidth when it can, resume, etc,
until it gets the file in.
