Prior to PC Tools firewall I tried the Outpost awhile back...Wasn't too bad at all, although I found it slowed down my XP laptop a bit...Using PC Tools firewall now with Avast 6, Spywareblaster, and Spyshelter free....Have to say this combo is awesome...Spyshelter itself acts as a firewall although its an anti Keylogger....Also works as spyware protection...Not much can go unnoticed by this software program...Very Fast, easy set up, easily adjusted...Works awesome....Just thought I'd share this info with someone....
   Cheers!!!! and safe surfing!!!
