newbie - keep getting notification of quarantined

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.
