Google Chrome remains after uninstall, unkillable process?

So I've uninstalled Google Chrome from the control panel due to some issues, and realized when trying to reinstall that the Google folder still remains, and there is a Chrome process running on startup EVERY SINGLE BOOT. I've attempted to kill it in task manager and tried other solutions, but to no avail. It says "access is denied" when trying to end the process, and it says "folder in use" when trying to delete the folder. It may be worth noting that I can still open chrome from this folder (even after its supposed deletion) but I CANNOT make it my default browser. If anymore info is needed, I'm happy to give it.
