What is it?
Ezula - ezstub.exe

What does it do?
Ezula primarily provides a browser addon that allows you to hold alt + click any word and it searches that term for you. It does help skip a step or two to save some time. I personally use Firefox and have a little google search box in the top right where I can toss something into and quickly search that way. For all of you super lazy people you may want to leave this installed but it will serve ads to you.
