comodo 3.0 is very easily killable by the task manager if it is installed without the defense+ or if the defense + is manually disabled after installation
so any weak trojan can very easily terminate the firewall and get access to outside
i think for this reason users are inforced to choose comodo installtion with the defense+ because if it was installed without defense+ it would be useless
when i installed comodo without the defense+ i could easily terminate both
cfp.exe
Cmdagent.exe
so it is very easy to bypass comodo protection if i choosed to install comodo without defense +
