Advice Request How Strong is Avast's Sandbox?

[BearHug]

Avast Premier has a Sandbox but I've never used it that's why I want to Know How Strong it is?

 

[Winter Soldier]

You consider that originally the sandbox was designed for the development, implementation and testing of programs, in order to test the operation without polluting a running operating system and then before applying the final changes.
Avast sandbox implements a very proven and strong technology, obviously with the limitations common to any software: bugs and possible vulnerabilities but at the current state, the sandbox is very secure.

Never had much luck with it, but you can look at the Sandbox settings.
Open Avast UI > Settings > Components > Sandbox > Customise.

Spoiler: My Advice

If you want to use it daily, try Sandboxie instead.
