Constant pop-ups about a Trojan affecting Cmd.exe but no detections w/ a scan?

It started today when I opened up steam and got a pop up saying We’ve blocked cmd.exe because it was infected with Win32:Agent-BDCC [Trj] I’ve ran full scans and nothing has shown up I have no idea what this is, is it a false positive?

Can you click on “See details” then post another screenshot,
(assuming the alert is repeatable).

You could also do a separate scan with Malwarebytes, but the affected file may have been quarantined by Avast.

Where exactly is the file located?

The legit cmd.exe should be in System32 and SysWOW64.
