Well Avast has already removed it, what more do you want to do? It can't do any harm to your PC seeing as it's already caught and isolated away.
If you're really paranoid, you can go to Avast -> Scan -> Scan for viruses -> Then at the bottom click "Quarantine (Virus Chest)" and delete it from there. And then maybe do a scan with Malwarebytes with Windows in safe mode just to make sure.
