Would you use a Firewall that had a cracked .dll?

So there is this new version of a firewall out, but the only crack for it is a cracked .dll, (it replaces the original .dll). Plus there is another firewall, and its crack requires that you patch the exe before it can read the liscence file.

I am very reluctatant to do anything but a serial # when it comes to firewalls. Most likley the person who made the crack is playing off your false-confidence and will use your modified firewall for his own purposes.

So again when it comes to firewalls only register by serial #, don't trust anything that modifies exe or dlls.


What do you think?
