Chrome on my Ubuntu keep hitting 100% CPU-usage after an update.
- I check Chrome Task Manager, where the 
Browsertask keep hitting 100% CPU usage. - The sympton persist even as I closed all the tabs.
 - I disabled all extensions
 - I sign out from Chrome
 - I try uninstall and reinstall without deleting the configuration, the system still persist
 
The only way to fix the 100% CPU usage into uninstall Chrome, delete the configuration files and reinstall Chrome.
Uninstall Chrome
sudo apt-get purge google-chrome-stableDelete Chrome configuration files
rm ~/.config/google-chrome/ -rfReinstall Chrome
Visit https://www.google.com/chrome/ using another browser

Download Chrome - Select 
64 bit .deb (For Debian/Ubuntu) - Click 
Accept and Install - I am using Lubuntu, so it promts 
Open with GDebi Package Installer(might differ if you are using Ubuntu) and continue to install the package.
