Avahi is NOT acting normally on your system.
> The Avahi mDNS/DNS-SD daemon implements Apple's Zeroconf architecture (also known as "Rendezvous" or "Bonjour"). The daemon registers local IP addresses and static services using mDNS/DNS-SD and provides two IPC APIs for local programs to make use of the mDNS record cache the avahi-daemon maintains.
I have it on my computers and have had no problems.
Unless you are networking with computers or printers via zeroconf, you
can probably remove it.
