Mac cleaning up windows viruses

Is it possible that Avast can clean up even windows viruses using a mac or is does it only clean mac viruses?

ie. Plug a USB on a mac from an infected windows. Does Avast mac clean up the USB no matter the threat?

Sorry for being redundant. Search anywhere doesn’t understand what I’m asking.

Thank you very much though. Have a nice virus free day
