Windows 10: Windows security Quick Scan not running

Ran a full scan a week ago then tried to go back to quick scan today. Quick scan will not run. Shows 35 hours to complete whatever scan is running. I canceled it and tried again, still no quick scan.

Windows Defender - Quick Scan

Windows defender no longer offers a quick scan option.

My options are:

• Scan
• Advanced Scan

• Full Scan
• Custom Scan
• Windows Defender Offline scan

Whichever option I check, the scan will need to run for hours to complete.

Is a quick scan available?

How do I restore this feature?

 

Does Windows Defender Quick scan interrupt Advanced scan?

Before I create a System Image, I run an Advanced scan using Windows Defender, and it typically takes about an hour and the Scan history lists about 4,000,000 files scanned. However, often I see only about 40,000 files scanned, what I get from a Quick scan.

I can think of two explanations that might account for this:

1. The Advanced scan completes, but a Quick scan starts afterwards and wipes out evidence that that the Advanced scan occurred (unless presumably some problem was found).

2. The Advanced scan is interrupted and a Quick scan runs.

Are there other possibilities?

The 2 possibilities listed above are both unsatisfactory because I can tell if an Advanced scan was completed. If an Advanced scan was just completed, there is no reason that a Quick scan should be run automatically.

 

Windows Security, list of scanned files

Hi

Regarding the new Windows Security app

Questions:

1) Where can I find a list of files included in latest (quick) scan.?

2) Where can I find a list of file type default not included in a scanning?

3) Where can I find the list of disks included in the next scanning?

Regards
