Can firewall block programs under avastsvc.exe?

I am using comodo firewall + avast 5 free.
Does anyone know if comodo will block the application if I tell comodo to block off internet access fo that exe but that exe uses avastsvc.exe (avast web shield) to gain access the internet? Meaning that the application is using avastsvc.exe as process name when show under active connections. (I cannot block avastsvc because most connections will be blocked.)
