What is Avid Virtual Instruments 10.3?

I was installing the PT11 update and noticed Avid Virtual Instruments 10.3 in my long list of available downloads. I don't recall installing it, and I've been keeping all my install files - it wasn't there. However, when I open PT and look at my instruments, I don't see anything that wasn't already there - Vacuum, Xpand, Structure, etc.



What was the +3GB I just installed?



Edit: Crap, I guess that was for PT10. Any idea how I can remove it?
