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.

A functioning periodic scanning button allows Windows Defender to work in concert

with third party anti-virus programs.

EDIT:

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

    If you are running another Anti-Virus like Avast as you said, that might be the culprit.

    Try uninstall Avast and restart your PC and see if problem persist?

    Using one or more real-time Anti-Virus software would cause conflict.

    I guess Avast replaced Windows Defender and that is why you are seeing such a message.

    Windows Defender is good Anti-Malware product, but you could also use Avast. It is up to you whether you are using Windows Defender or Avast, but I would say Windows Defender is good Anti-Virus.

    You may uninstall it using Add or Remove Program, and if problem persist, use removal tool.
