Open ports in my router, can anyone helpme please?

I recently downloaded the fing app, because my devices have behaved strangely, I looked for open ports on my internet router and there are 3 that should not be there:
they are all related to something called blackice icecaps, blackice alerts, sun-answerbook, could someone tell me what this is about? I am new to this forum and I would like both to help and to be helped but honestly, where else to ask, greetings friends! and I await your answers, please, it is important to me, and it would mean a lot.
