newbie - keep getting notification of quarantined

[REDACTED]

Hi, a device keeps getting a file quarantined.  It's the same file every time.

mwxbkbxe.tf
C:\Windows\System32\mwxbkbxe.tf
Win32:Confi [Wrm]

I'm getting a little nervous that it keeps coming back.  I have done a scan with malwarebytes, but thats about it.  Still comes back.  What would be the next steps as I am a completey new to this. 

Thank you very much.
