I am getting what seem to be random popups instructing me to reinstall the Norton Toolbar from the Chrome Web Store.
See the screen capture in the attached PDF below.
Popups can appear once or twice a day but not every day.
Sometimes the popups don't show for a few days
I always choose "Install now".
It happens even though Chrome has NOT been updated (version numbers unchanged).
The only consistent thing is that the popups show after resuming from hibernation or restarting.
This is happening on 2 Windows 7 laptops and 1 Windows 8.1 laptop.
Is all this a virus, a glitch in NIS or a glitch in the Chrome extension?
