Windows 10: Hi, my windows defender said it found a trojan that it could not quarantine it

My defender stated that it found a trojan it said it couldn't quarantine it, i check after with avast and with Malwarebytes, does can't seem to find it, but i noticed that my C: is losing some space bit by bit. Do you guys know how to check the report, i can't find it so to at least look for the file to see if it still there of it has been taken care of

:)

 

Recurrent trojan, HTML/Phish quarantined by Windows Defender, and don't have active option/button to remove as suggested.

Hi Adrianne,

Thank you so much for your reply.

Your info re: "a version update does not provide a clean install" is helpful to know.

I have run the Windows Defender Offline, but never tied running it to the means of removing quarantined files.

In regards to Windows Defender providing file details after a scan, with the suggestion to remove the file, but with no obvious way to do so, like a "remove threat" button, I'm still a little befuddled. Is running the
Windows Defender Offline scan, after I get that suggestion to remove the quarantined file, the one and only way that file is going to be removed? If so, that needs to be made more obvious to the end user, because in my current version, we're given a suggestion
to remove the offending file, but with NO obvious way to do so...not even the instruction that running Windows Defender Offline is the next step to take to remove it.

I'm also curious why this Trojan keeps appearing in C:\Users\3orch\AppData\Local\Packages\microsoft.windowscommunicationsapps_8wekyb3d8bbwe\LocalState\Files\.

Is there a Windows app that is making itself a vector online for this trojan?

Again, thank you for your kind reply. I look forward to additional enlightenment.

Kind Regards,

 

Trojan in Allowed Items and Quarantines

Windows Defender detected a Trojan Virus on a full scan. When I reviewed the history it indicated that the Trojan was in "allowed threats" as well as in "quarantined threats." How could that happen? How can I find out if the virus was removed?

Why did Defender not quarantine thie Trojan it discovered? - trojan Rogue:JS/TechBrolo.A

Defender has found - trojan Rogue:JS/TechBrolo.A - but it will not, or can not quarantine it, what should I do. ...I tried AVG but it did not find the issue at all ... ?
