Licensing and Activation Q's

If Comodo Firewall is free, then why do you have to register and activate it? Also, is crypserv.exe a part of the firewall or licensing? Is it required for the firewall to function? I just don’t see the need to use extra resources when the product is free in the first place.

Welcome to the forum.
The registration and activation is to keep track on how many users they have, so they know how popular the firewall is.
They are working on a new activation, that takes place auto when you install or something like that, so you wont have to get an activation key.

I have never seen crypserv.exe on my PC, so I don’t think it’s Comodo.
It seems to belong to CrypKey software. Do you use another software that’s protected by CrypKey?

So far as I know, I don’t have anything else installed that should be using crypserv. Guess I’ll kill it and see if it affects anything. Thanks.
