Trojan:Win32/Zpevdo.B is active and action cannot be taken

[Frowley]

I downloaded a file from a friend which contained the virus Trojan:Win32/Zpevdo.B (according to windows defender). I tried to quarantine and remove it but it keeps popping up 1 second after I do it and the status is active. I've read about multiple ways to remove it and none have worked.


It just stays on Threat found - action needed and I've tried Malwarebytes as many recommended and I got a few things that I quarantined but windows defender still gives me the pop up about the trojan, I've tried Farbar recovery scan tool (although unsure if scanning was all I was supposed to do?) and last, I tried MSERT. It also says "Active threats have not been remediated and are running on your device." I've scanned many times and nothing seems to change ?

Unsure of how to remove it. Thanks in advance.
