a problem that i have never heard before

i have used cis for a long time,today i met a problem that i have never heard before.i installed a software on my computer,and try to run it.i found there is no alert from the firewall to ask me wether i should allow the connection to the internet from this software or not. and of course,later i found this software could not connect to the internet untill i manually added rules for this software at cis.then i installedl another software on my computer,still the same problem that cis no longer detect new software on my computer which will connect to the internet.so what’s wroung with my firewall?

What level is your firewall’s security? And check whether your application digital signer is listed in the trusted vendors list (Defense+ > My Trusted Software Vendors).
