Sometimes AutoSandbox pops up after the app is installed & opens. In this scenario, I think the apps are not deleted & one has to manually delete/uninstall the apps if found malicious, right?

Why sometimes AutoSandbox dont pops up at the start but after completed install & apps opening?

Does this means the analyzers didn’t find anything suspicious during install but on the opening?

But its good, easier, suitable & safe if AutoSandbox pops up at the very start i.e at the start of installation.
