how to get rid of black toolbar at bottom of google chrome?

[Jeffry Helms]

Its probably a pop up spam virus--make a new user account and delete the infected one---by clicking the icon picture at the top right of your start menu and following the links-make sure your security is on, your windows firewall square checkboxs should be both checked to avoid incoming virus's etc.---you can find your windows firewall off the control panel security links.--if all else fail, do your windows update, and scan with windows defender, then on your control panel window--follow the links to uninstall any unwanted programs, good luck.
