The SafeZone Browser (used for on-line banking/shopping, etc.) is now a part of avast Free, previously this was only available in the paid versions of avast.
It sounds like your best option would be to do a custom install when installing avast, that way you can choose what elements/components you want installed. I guess having installed the SafeZone browser the folders have been created, looks like removing the safezone component doesn’t remove the folder. The folder without the browser is essentially inert.
I didn’t install the safezone browser to start with and I can find no safezone folder on my win10 system.
One of the things malware tries to do is disable your AV so it has unfettered access to your system the avast self-defence module helps to prevent this, so yes it is important.
