i have went back to using cpf 2.4 i have a windows xp machine sp2 fully updated the only other security i have on it is avast av,windows defender and comodo memory firewall. and cpf 3 takes about 5 minutes before the icon loads in the system tray on restarts leaving me feeling like i am unprotected till then i dont feel any of my other security is causing the problem because cpf 3 took that long to load before the other security was installed.
Windows Defender is no good. If you look at your task manger while booting you will see Comodo is already running. Sometimes the icon is not loaded but you are being protected. I high doubt its 5 minutes also.
