I have finally installed the trial version of DefenseWall. Here are some questions: 1) It is recommended that I install DW on a clean system. What if the system isnt clean? What is the downside of this? 2) Will DW conflict with WinPatrol? 3) Can I add other programs to untrusted such as msn, office, adobe, etc? This should provide me with extra protection right? 4) Anything else a newbie ought to know? 5) Can I add Sbie as untrusted?
