How to tell if a visitor's browser is using Google tool bar?

It is easy to see if visitor's browser is using Alexa tool bar.

My question is:
How to know if a visitor's browser is using Google tool bar?

i dont think it is possible

 

I too think that it is not possible to track if the visitor has installed Google Toolbar or not?

 

What are you going to do by finding it. Whether it will return any results.

 

I just found this: read UserAgent

I learned from ~CReed

GTB is google tool bar
