Windows 10: Quick scan shows a threat, full and offline scans do not?

Protection history shows: "Detected: Trojan:Win32/Nibtsec!tskStatus: Quarantine failedThis threat or app might not be completely remediatedAfflicted items:file: C:\Users\anes1\AppData\Roaming\Mozilla\Firefox\Profiles\l05f4g6l.default-release\storage\default\moz-extension+++43e6cbab-5589-48db-88d5-6de15d0eb29d\idb\2325712684IbDdB-FBiDl-eesgSatro.files\36653"but my Virus and Threat Protection 'page' shows:"Current threatsNo current threatsLast scan: [date and time] quick scan1 threats found.Scan lasted 2 minutes 29 seconds28493 files scanned."...so what gives? What should my next steps be?Th

:)

 

no record of defender offline scan

Thank both of you for replying.

There is no "Scan History" but there is a "Threat History", clicked on that and saw "Full History" which simply said there were not threats.

No history of the last scan other than that 3 day old quick scan

I looked that web page listed above and tried the following that showed no response

PS C:\WINDOWS\system32>

PS C:\WINDOWS\system32> Get-MpThreatDetection

PS C:\WINDOWS\system32>

I am running a full scan now. I would have expected that a record of the offline scan would have shown up in history, not just "no threats"

Recent update was the humongous 1903 Feature update.

[EDIT] Full scan just completed and the history was updated. It seems your off-line scan does not report to defender like the quick or the full.

 

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 Offline Scan results?

Just did a Windows Defender Offline Scan and wondering what the results are?
All it showed during the scan was how many files are being scanned and the percentage completed.
That is all.

Even if no threats were detected, at least it should notify that no threats were detected during the Offline Scan.
