Yes, indeed, malarkie is right! This process should be deleted. As far as I know you can´t deinstall it without having serious problems on your computer. Just try to deinstall ITunes and if all works fine, don´t update your player again. Because BonjourService will be installed than again. I found something else wich is called "TurnoffBonjour.exe". That´s a program wich deinstalls Bonjour. But I won´t give any guaranties if it works, because I´ve never tried it. And as malarkie just mentioned, look at all these processes wich are in use and deactivate those you don´t really need. About updating programms: Allways think about if it´s really necessary if some programs like ITunes for example should be updated as long as they work.
