I've used Zone Alarm Pro and Zone Alarm Internet Security Suit and Win One Care.
In comparison to these two its
cr@p Imnot talking about features. It may be good in that department.I found it slowing down my computer for no reason at all ( mindwell Zone alarm doesnt slow down my pc ). Installing is a pain. If you have to uninstall it then you have to redownload the complete thing again.
Overall I would recommend you to either of what Ive used. There is a free version of Zone Alarm available too. Plus W1C integrates with windows one thing I dont like .
