New Defender Platform 4.18.2003.4-0 - Items skipped during scan Alert
----- Update March 25, 2020 ------
Now Fixed by Microsoft's latest platform: 4.18.2003.8-0
Update KB4052623: Microsoft fixes Defender Scan Skip Bug
Just received the latest Defender Platform 4.18.2003.4-0 on both machines in the early AM of Tuesday the 10th, 8 hours before .719 was released but right after this Defender 4.18.2003.4-0 Platform update.
Both received this new alert message about skipping an item during a Quick Scan - 'scan skipped an item due to exclusion or network scanning settings'.
I have no exclusions!
And, I have never made any changes to my network scanning settings that I know of. Everything under WD's 'Firewall and network protection' is default 'ON'
Anyone else seeing this?
After further tests by re-imaging my machine back to before this platform update, and then running a scan and NOT seeing this '...scan skipped an item' message, and then updating just the platform, and AGAIN immediately seeing it reappear, I'm certain this is tied to this latest 4.18.2003.4-0 platform update, and in any subsequently released platforms, 4.18.2003.5-0 and 4.18.2003.6-0 now seen 2 weeks later by others, and regardless of the monthly CU's
This issue is triggered for some by any of the Window's Defender Platform updates after and including, 4.18.2003.4-0, and is not due to a virus or a CU, but a change by Microsoft's in the default network scan setting in newer Defender platform engines.
It seems that in the older Windows Defender engines, network scanning was enabled by default, which apparently for some reason Microsoft's documentation does NOT recommend:
" -DisableScanningNetworkFiles
Indicates whether to scan for network files. If you specify a value of $False or do not specify a value, Windows Defender scans network files. If you specify a value of $True, Windows Defender does not scan network files. We do not recommend that you scan network files."
