High resource consum in Comofo fw i only want to use virtual kiosk not all fw

YesI try i try and i try to use comodo fw because i love virtual kiosk because i can test programs here, legitimate programs who dont works on sandboxie. I think the v kiosk system are very good but it consums too much resources I think disable anything on fw and only use v kiosk. Is that posible? I try it one time and see in registers somehings like conections and another things. I use panda cloud av and plain to use untheart av because comodo av was to heavy to my machine. Can you help me to configure fw or tell me if i disable anything can i use vkiosk alone and windows fw? I know comodo is better but for me is to heavy
