Avast Installer Keeps asking me to reboot

Uninstalled Avast Free Version to get Safezone Browser off my computer. Tried to remove it without uninstalling avast but could not figure out how.

When I try to reinstall avast, avast installer keeps asking me to reboot. I have turned my computer off twice so far. What’s the deal?

If not, read and follow instructions

You didn’t say, but if you are running Windows 10, merely shutting down the system does not amount to a restart, due to how fastboot in Win10 is set up. https://duckduckgo.com/?q=fastboot+in+win10&t=ffab&ia=web

You’d actually have to do a restart to have your system shut down completely and then start again.

Still stuck with Avast SafeZone? https://forum.avast.com/index.php?topic=93544.msg1305451#msg1305451 Posted April 7, 2016.
