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?

 

Windows Defender Quick Scan question

I just did a quick scan on my computer, when it was done in notifications area got message: Windows Defender scanned your PC At 1:42:10 on 2/28/2017 and took action against malicious software, but the windows defender screen said: Scan completed no threats
detected during this scan. There is nothing listed in the history either, what does this mean?

 

Windows Defender quick scan fails to complete

When I try to employ a "Quick Scan" procedure in Defender, the scan progress indicator, coloured green, stops half way and does not complete.

The files scanned number continues the count as if it is doing a full scan.

My Windows 10 updates are correct as our the virus definitions etc.

Any suggestions on why the "quick" scan fails to complete?

Thanks
