"Free, quick install"
Quick Install, you don't need to worry anything
Pop ups and alarm from program internet access
pop-ups of its program update/promotions.
I have been using Zone Alarm for many years. The latest version is running on Win 7 pro. No crash down from install to now. It is could be a good alternative for free firewall.
But there is one thing I hate most is the programs will pops up their promotion windows. It does not happen in the older version. I hate these pop up and wishing to know how to turn them off.
However if I need to purchase a fire wall, Zone alarm won't be my first option.
