As some people on Techspot, occasionally complain that the ubiquitous Zone Alarm is less than perfect,I decided to check out Comodo firewall.Here are my random comments - The good points : 1.It`s free. 2.It installs easily on my P.3 XP SP1 machine. 3.Appears to use even fewer resources than ZA. 4.The default settings seem about right,except for the Application behaviour monitoring, which could be turned off 5.Has plenty of paranoia settings,for those who are that way inclined. 6.I like it better than ZA or Kerio and will to continue to use it,until blows up my system for no apparent reason. The not so good points : 1.It`s more complicated than ZA,so for a complete novice,it could be offered as a possible alternative to ZA,rather than a definite replacement. 2.It`s so "quiet",it`s sometimes difficult to know if it`s actually working at all (it is). 3.The developers still haven`t paid me yet.
