I just installed Comodo firewall (I am presently using Zone Alarm Pro and yes, it is the latest version) and when I attempted to sync my Cingular 8525 my system restarts. When my system starts up, I closed Zone Alarm and run Comodo as a stand alone each time I crashed. My OS is XP Pro with SP2. I was unable to keep my system running with Comodo (could not even use Firefox) so I had to uninstall it. The S/W looks pretty functional and easier to configure than Zone Alarm but I cannot survive all the restarts. Suggestions?
