Hi Michael,

I believe that your IT department is right.

It is probable that the problem in v1803 is associated with the "Periodic Scanning"

button. Please see my posts in this thread for August 27 and 28.

I think there is a fault in v1803, that leaves only some PCs without a functioning

periodic scanning button.

In other threads, some have had this same problem, and their button was turned on.

Yet, when they uninstalled their third party anti-virus, there problem was corrected.

functioning periodic scanning button allows Windows Defender to work in concert

with third party anti-virus programs.


I did not have this link in hand when I first replied to your post.

This link is my case in point.

Andrew had the same problem, that was originally expressed in this thread.

He had also been successfully running a third party security program, in concert with

Windows Defender, until W10 v1803 was installed. And his periodic scanning button

was turned "ON".

Pay particular attention to the second page of his thread. 

Regards,  Glen
