You're right: Comodo overwhelms the average user with excruciating details, and no meaningful information.
Zone Alarm isn't quite so bad; but it too can notify about some obscure process and be less than informative.
The root problem is these thousands of processes are never named exactly what they are or do: that goes for legit Windows (or OS) or non-legit items.
Often it's a matter of trust, whether to let one proceed.
Kerio Sunbelt Personal is another FW of moderation.
Even Windows on board is not too bad, but lacks (In some situations) outbound defense.
All block unrequested inbound packet intrusion; it's the outbound stuff that can be troublesome, because once your browser has "reached out" (deliberately by you, or as "automatic" by configuration) and asked for an asset: the return packet is configured correctly and verified as legit.
Browser "hardening" is the key to reign in these automatic asset requests.
Don't fetch 3rd party assets (turn off 3rd party cookies) and don't permit 'active scripting' from returning assets.
Firefox has these mod's with the correct add-on's & configurations.
IE is way too liberal with them and falls victim to the slightest manipulation.
With that arrangement the firewall becomes easier to manage.
