user manual

hi!

i installed comodo just a few days ago. i am rather a beginner concerning computers. is there a user manual for cpf (explaining the alerts etc.)?

when i installed comodo the first time, i forgot to get rid off my other firewall. comodo could not install completely and i had to uninst it. however, there is no unwise.exe for comodo. why not?

please excuse my bad english. i am coming from germany so i am not a native speaker

best wishes,
ab
