mse detects something, tries to quarantine it but fails, and now it doesnt detect anything

[MysteryBox]

so i downloaded something, and then i tried to move the file to a different location, but mse warned me that it was a "VirTool:Win32/Obfuscator.XZ". mse tried to quarantine it but it gave me an error. i exited out of mse, and ran a quick scan with mse and mbam but both detect nothing.

heres some stuff mse says under "history"

detected item: VirTool:win32/obfuscator.XZ
alert level: severe
