artsd is the Sound Server for KDE, so no, it wouldn't happen in Gnome
You could do a few things that are generic:
chmod a-x /usr/bin/artsd
Then it cannot be executed.
Find which package contains artsd, and if you don't need any apps in it:
rpm -e packagename
You can set it's execute bit only for root, own the file to only root and chmod so only root can execute it (better off with the first chmod thing above).
Or you can dig through your scripts and see what (if anything) is starting it. If it's KDE core, then you could (theoretically as it would probably be quite an effort) dig through the code and gut it.
Cool
