ok let me explain why im giving this a 2 star rating. this is not the best firewall period free or pay. ur basically paying for a dumbed down version of comodo which is free. if u have to pay for 1 then get kerio, it uses less resourses, anyone can use it and it conflicts with very few products. i would rather have za free which is why i gave it a 3 and this a 2. neither r worth having since comodo is like i said a better version of za, they both have the pop-ups and everything. so best secure go with comodo, most user friendly go with kerio. either way, paying for this makes no sense
