I really liked nothing about comodo… :-X

Stuff I would look out for in a firewall:
1> Quick startup
2> Low resource Utilization
3> Ability to manually choose which protocols to allow and block (like with guarddog under linux http://simonzone.com/software/guarddog/#screenshots)
4> Be totally seperate from my Antivirus
5> Set it forget it. I dont mind if it asks a lot of questions during its ‘training’ period but once set up it should ask minimal questions.

When is the avast PF comming out neway?
