HELP!!! Avast Firewall NDIS Filter Miniport

My printer stopped printing. It seems even after I uninstalled avast with ASWCLEAR it left this little nugget behind: Avast Firewall NDIS Filter Miniport. My printer is hardwired into my router. I thought I removed this pest after a troubleshooter alerted me to its presence but the printer still does not work. Need help with this please. I’m running windows 7 64bit.
