Should I swtich to Comodo Pro?

I’m swtching from ZA free and have a few questions. I have an Inspirion 9300 w/ XP Home SP2, AVG Free, ad aware and spy bot. I also recently downloaded IE7. I’ve never used another FW expect ZA Free.

My questions are- is there anything above that is not compatable w/ Comodo Pro?

  • How do I learn what to set up once I install Comodo Pro? In ZA i didn’t have any set up
    -Is this compatable w/ multi users? We have on user w/ full priveliges and 2 limitied users
    TIA for you help-
