Jabber
I Don't want Jabber. Why did iI get an u invited buddy request? Does this mean my system is compromised?
MacBook Pro (Retina, 13-inch,Early 2015), iOS 9.0.2
If you don't want jabber, don't install it.
It is not part of OS X nor does it come installed by Apple.
Where did you receive the buddy request, email?
