ZoneAlarm Extreme Security ForceField/downloading malacious vids...

Hi all,

I was going to post this in the ZoneAlarm forum also but thought I would here too. If someone were to download a video using a YouTube type downloader (or even Jaksta, Applian (though I think they bought Jaksta?) etc.) or record a streaming vid on another site(s), how does Z.A's ForceField virtual browser feature handle this in case the streaming vid that is being downloaded ends up being malacious? Would is still in theory catch this in the virtual browser?
