The icon in the system tray had a small blob on it indicating that some kind
of attention was needed, so I clicked on the icon to see what it was.

When the window popped up, it indicated that "You haven't scanned your
computer in 3 days. We recommend that you schedule Windows Defender to scan
your computer each day." There was a "Start Scan" button displayed.

I clicked the "start scan" button and received the following error in a
popup labled "Windows Defender":

Windows Defender encountered an error: 0x800040003. Invalid pointer

An "Ok" button was displayed. I clicked on the button, which closed the
error window and left the "Start Scan" button grayed out.

I closed the Windows Defender window and then attempted to retrace the steps
which caused the error. From the point that I saw the blob on the system
tray icon, the same steps produced the same results.

Once I repeated the steps and got the same results, I tried scanning using
the scan button on the toobar instead. Windows Defender then scanned my
system without further incident.
 
Possibly a difference between the Quick Scan which only scans certain
locations commonly populated by spyware and a Full Scan which examines
every file on your system. The Msft recommended scheduled scan is the
Quick Scan. You very possibly have a trace of old malware resident in
either System Restore, a Compressed File (as in zipped), or a Quarantined
file from Defender or another scanner. None of these is cleanable using
Windows Defender, but all are manually cleanable/removable.

You can look at the system event log to see exactly where the file/s that
gave you the 80004003 error code is located (as documented repeatedly in
this forum) and make that decision.
 
The problem was not with something the scan found, it was with starting the
scan. That silly scan button has never worked and is a known bug. Just use
the scan option on the toolbar to chose quick,full, or custom scan and all
will be well.
