AVAST HOME wont start

AVAST home program won’t start up, icon showsred circle with slash in it. ???

Need a bit more information.

What is your operating system, avast home or pro, other security programs running, previous anti virus program(s) and how you uninstalled them, and a bit about your computer.

Did avast ever run? Or is this a new install?

Welcome to the forum!

Have (or did) you have another AV installed in this system, if so what was it and how did you get rid of it ?

The red circle is usually accompanied with error messages, if so, what were they ?
