Google Chrome Norton Toolbar Issue

I have a couple issues with the toolbar in Google Chrome and was wondering if anybody else ran into this and aware of a fix.

Google Chrome version 39.0.2171.95

1. Although the toolbar icon shows up, there is no toolbar.

2. Memory usage of the extension is insanely high and does not release after closing all Chrome windows. The Chrome Task Manager is currently reporting the extension at 860MB and 25-28% CPU utilization.

I am thinking about uninstalling the toolbar extension. In doing so, will I still be protected while browsing the web with Chrome?
