how to remove a trojan threat that is Quarantined

On the page it does not say remove threat anywhere. So how do I remove a Quarantined Trojan and i have 2 of them got at the same time. Both the same Trojan.

 

How do I remove quarantined threats

Windows Defender did what it is designed to do - quarantined a Trojan. Now I would like to remove it from quarantine. How do I do that? I know Windows says it will removed periodically, but I do not know how long that may be, so would like to manually get it off of my system now.

The quarantine history also lists the same threat 3 times with the same date. Does that mean it tried to enter my system 3 times in the same day?

 

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?
