Unknown Sources Enabled on Android 8

Akash thanks for responding,
Unfortunately this is occurring on my phone and the instructions sent were for how to take the screen snapshot on Windows, As I indicated, I have Android and have no idea how to take a screen snapshot ?   Or how to update this post with them if I did ?

The AVG message is:  Warning:  Issues detected.  
When I double press on that it takes me to an AVG screen that indicates: Unknown sources enabled.  
The options are to RESOLVE or IGNORE.  
When I press RESOLVE it takes me to a place that used to have control in the phone's settings for allowing downloads from other than the Play Store.  But those settings have moved in Android 8.  I located them in Settings and, as I indicated, it lists  Chrome, Drive and Gmail as potential apps where you could download from other than the Play Store, However, all indicate NOT ALLOWED, so I have no idea why the AVG softare thinks my phone has Unknown sources enabled ?

I just installed Android 8 Oreo on my phone.  As soon as I did, I got a message from AVG indicating "Unknown Sources Enabled".  When I try to resolve it, it does not show any unknown sources enable.  It show Chrome, Drive and Gmail as potential vehicles to install unknown sources. but it also indicates they are "not allowed.   Has anyone experienced this and resolved it ?

Alan,
I first searched the AVG website looking for an email address to post my support question, but could find none. That's why I started this community questions.
Can you please tell me what email address I can use to get support for this issue.

Thanks.

Akash,
Thank you for the infrmation and the follow up, but that is not the issue.
I had found the new places and names before opening this post.
The issue is that AVG thinks that I have "Unknow sources enabled" and it produces a message stating that.
But I can find no place where I might have that setting.
As I stated, all 3 of the apps listed under "install other apps" are marked as "Not Allowed".
So why does AVG think I have "Unknown sources enabled" ?
