File containing URLs to be Blocked?

Is there any file or way to tell Avast to block certain URLs other then inputting them manually in WebShield config. Blocking via Avast is fast and does not require any system reboot. Editing Windows “Hosts” file requires rebooting. Also I don’t want to install any additional software for URL blocking as Avast is quite capable of doing it. I found an old thread here which suggests editing avast4.mdb file.
That thread is very old and newer methods/tricks may be available in current versions of Avast.

Please advice.

Thanks…

Editing Windows "Hosts" file requires rebooting.
That's not true.

You can edit the HOSTS file at any time but you have to stop and restart the browser to have it reloaded.

HOSTS files I use:

Managed with HostsMan and I use its HostsServer proxy to speed up browsing:

I don’t think there’s a file where you can update the list of blocked URLs.

Thanks for correcting me…
